Change the Perl scripts to turn on lexical warnings instead of setting
the global $^W variable via the -w switch.
The -w sets warnings for all code that interpreter runs, while "use
warnings" is lexically scoped. The former is probably not what the
authors wanted.
As an auxiliary benefit it's now possible to build Git with:
PERL_PATH='/usr/bin/env perl'
Which would previously result in failures, since "#!/usr/bin/env perl -w"
doesn't work as a shebang.

Formalize our dependency on perl 5.8, bumped from 5.6.[12]. We already
used the three-arg form of open() which was introduced in 5.6.1, but
t/t9700/test.pl explicitly depended on 5.6.2.
However git-add--interactive.pl has been failing on the 5.6 line since
it was introduced in v1.5.0-rc0~12^2~2 back in 2006 due to this open
syntax:
sub run_cmd_pipe {
my $fh = undef;
open($fh, '-|', @_) or die;
return <$fh>;
}
Which when executed dies on "Can't use an undefined value as
filehandle reference". Several of our tests also fail on 5.6 (even
more when compiled with NO_PERL_MAKEMAKER=1):
t2016-checkout-patch.sh
t3904-stash-patch.sh
t3701-add-interactive.sh
t7105-reset-patch.sh
t7501-commit.sh
t9700-perl-git.sh
Our code is bitrotting on 5.6 with no-one interested in fixing it, and
pinning us to such an ancient release of Perl is keeping us from using
useful features introduced in the 5.8 release.
The 5.6 series is now over 10 years old, and the 5.6.2 maintenance
release almost 7. 5.8 on the other hand is more than 8 years old.
All the modern Unix-like operating systems have now upgraded to it or
a later version, and 5.8 packages are available for old IRIX, AIX
Solaris and Tru64 systems.

The "a" and "d" commands to ‘add --patch’ (accept/reject rest of file)
interact with "j", "g", and "/" (skip some hunks) in a perhaps
confusing way: after accepting or rejecting all _later_ hunks in the
file, they return to the earlier, skipped hunks and prompt the user
about them again.
This behavior can be very useful in practice. One can still accept or
reject _all_ undecided hunks in a file by using the "g" command to
move to hunk #1 first.

When we look at a patch for adding hunks interactively, we
first split it into a header and a list of hunks. Some of
the header lines, such as mode changes and deletion, however,
become their own selectable hunks. Later when we reassemble
the patch, we simply concatenate the header and the selected
hunks. This leads to patches like this:
diff --git a/file b/file
index d95f3ad..0000000
--- a/file
+++ /dev/null
deleted file mode 100644
@@ -1 +0,0 @@
-content
Notice how the deletion comes _after_ the ---/+++ lines,
when it should come before.
In many cases, we can get away with this as git-apply
accepts the slightly bogus input. However, in the specific
case of a deletion line that is being applied via "apply
-R", this malformed patch triggers an assert in git-apply.
This comes up when discarding a deletion via "git checkout
-p".
Rather than try to make git-apply accept our odd input,
let's just reassemble the patch in the correct order.

Commit 24ab81a fixed the deletion of empty files, but broke
deletion of non-empty files. The approach it took was to
factor out the "deleted" line from the patch header into its
own hunk, the same way we do for mode changes. However,
unlike mode changes, we only showed the special "delete this
file" hunk if there were no other hunks. Otherwise, the user
would annoyingly be presented with _two_ hunks: one for
deleting the file and one for deleting the content.
This meant that in the non-empty case, we forgot about the
deleted line entirely, and we submitted a bogus patch to
git-apply (with "/dev/null" as the destination file, but not
marked as a deletion).
Instead, this patch combines the file deletion hunk and the
content deletion hunk (if there is one) into a single
deletion hunk which is either staged or not.

Usually we show deletion as a big hunk deleting all of the
file's text. However, for files with no content, the diff
shows just the 'deleted file mode ...' line. This patch
cause "add -p" (and related commands) to recognize that line
and explicitly ask about deleting the file.
We only add the "stage this deletion" hunk for empty files,
since other files will already ask about the big content
deletion hunk. We could also change those files to simply
display "stage this deletion", but showing the actual
deleted content is probably what an interactive user wants.

This adds a hunk-based mode to git-stash. You can select hunks from
the difference between HEAD and worktree, and git-stash will build a
stash that reflects these changes. The index state of the stash is
the same as your current index, and we also let --patch imply
--keep-index.
Note that because the selected hunks are rolled back from the worktree
but not the index, the resulting state may appear somewhat confusing
if you had also staged these changes. This is not entirely
satisfactory, but due to the way stashes are applied, other solutions
would require a change to the stash format.

This introduces a --patch mode for git-checkout. In the index usage
git checkout --patch -- [files...]
it lets the user discard edits from the <files> at the granularity of
hunks (by selecting hunks from 'git diff' and then reverse applying
them to the worktree).
We also accept a revision argument. In the case
git checkout --patch HEAD -- [files...]
we offer hunks from the difference between HEAD and the worktree, and
reverse applies them to both index and worktree, allowing you to
discard staged changes completely. In the non-HEAD usage
git checkout --patch <revision> -- [files...]
it offers hunks from the difference between the worktree and
<revision>. The chosen hunks are then applied to both index and
worktree.
The application to worktree and index is done "atomically" in the
sense that we first check if the patch applies to the index (it should
always apply to the worktree). If it does not, we give the user a
choice to either abort or apply to the worktree anyway.

which acts as the opposite of 'git add --patch -- [files...]': it
offers hunks for *un*staging. Advanced usage is
git reset --patch <revision> -- [files...]
which offers hunks from the diff between the index and <revision> for
forward application to the index. (That is, the basic case is just
<revision> = HEAD.)

In 0392513 (add-interactive: refactor mode hunk handling, 2009-04-16),
we merged the interaction loops for mode changes and hunk staging.
This was fine at the time, because 0beee4c (git-add--interactive:

However, in 7a26e65 (Revert "git-add--interactive: remove hunk

would attempt in vain to merge mode changes with diff hunks,
corrupting both in the process.
We add a check to the coalescing loop to ensure it only looks at diff
hunks, thus skipping mode changes.

The original implementation considered the mode separately
from the rest of the hunks, asking about it outside the main
hunk-selection loop. This patch instead places a mode change
as the first hunk in the loop. This has two advantages:
1. less duplicated code (since we use the main selection
loop). This also cleans up an inconsistency, which is
that the main selection loop separates options with a
comma, whereas the mode prompt used slashes.
2. users can now skip the mode change and come back to it,
search for it (via "/mode"), etc, as they can with other
hunks.
To facilitate this, each hunk is now marked with a "type".
Mode hunks are not considered for splitting (which would
make no sense, and also confuses the split_hunk function),
nor are they editable. In theory, one could edit the mode
lines and change to a new mode. In practice, there are only
two modes that git cares about (0644 and 0755), so either
you want to move from one to the other or not (and you can
do that by staging or not staging).

After invoking git add -p I always got the warnings:
Use of uninitialized value $_[3] in exec at Git.pm line 1282.

A bisect showed that these warnings occur in a301973 "add -p: print errors

They can be reproduced by setting color.ui (or color.interactive) to "auto"
and unsetting color.interactive.help and color.interactive.error.
I am using Perl 5.10.0.
The reason of the warning is that color.interactive.error defaults to
color.interactive.help which defaults to nothing in the specific codepath.
It defaults to 'red bold' some lines above which could lead to the wrong
assumption that it always defaults to 'red bold' now.
This patch lets it default to 'red bold', blowing the warnings away.
