The rule for "git-instaweb" depends on "gitweb". This makes
no sense, because:
1. git-instaweb has no build-time dependency on gitweb; it
is a run-time dependency
2. gitweb is a directory that we want to recursively make
in. As a result, its recipe is marked .PHONY, which
causes "make" to rebuild git-instaweb every time it is
run.

2009-08-11) special cases git-pull on an unborn branch in a different

It's better to start the man page with a description of what
submodules actually are, instead of saying what they are not.
Reorder the paragraphs such that
- the first short paragraph introduces the submodule concept,
- the second paragraph highlights the usage of the submodule command,
- the third paragraph giving background information, and finally
- the fourth paragraph discusing alternatives such as subtrees and
remotes, which we don't want to be confused with.
This ordering deepens the knowledge on submodules with each paragraph.
First the basic questions like "How/what" will be answered, while the
underlying concepts will be taught at a later time.
Making sure it is not confused with subtrees and remotes is not really
enhancing knowledge of submodules itself, but rather painting the big
picture of git concepts, so you could also argue to have it as the second
paragraph. Personally I think this may confuse readers, specially
newcomers though.
Additionally to reordering the paragraphs, they have been slightly
reworded.

The config-writing code uses xmmap to map the existing
config file, which will die if the map fails. This has two
downsides:
1. The error message is not very helpful, as it lacks any
context about the file we are mapping:
$ mkdir foo
$ git config --file=foo some.key value
fatal: Out of memory? mmap failed: No such device
2. We normally do not die in this code path; instead, we'd
rather report the error and return an appropriate exit
status (which is part of the public interface
documented in git-config.1).
This patch introduces a "gentle" form of xmmap which lets us
produce our own error message. We do not want to use mmap
directly, because we would like to use the other
compatibility elements of xmmap (e.g., handling 0-length
maps portably).
The end result is:
$ git.compile config --file=foo some.key value
error: unable to mmap 'foo': No such device
$ echo $?

Once upon a time, git's in-memory representation of a cache
entry actually pointed to the mmap'd on-disk data. So in
520fc24 (Allow writing to the private index file mapping.,
2005-04-26), we specified PROT_WRITE so that we could tweak
the entries while we run (in our own MAP_PRIVATE copy-on-write
version, of course).
Later, 7a51ed6 (Make on-disk index representation separate
from in-core one, 2008-01-14) stopped doing this; we copy
the data into our in-core representation, and then drop the
mmap immediately. We can therefore drop the PROT_WRITE flag.
It's probably not hurting anything as it is, but it's
potentially confusing.
Note that we could also mark the mapping as "const" to
verify that we never write to it. However, we don't
typically do that for our other maps, as it then requires
casting to munmap() it.

Traditionally, we only cared about whitespace breakages introduced
in new lines. Some people want to paint whitespace breakages on old
lines, too. When they see a whitespace breakage on a new line, they
can spot the same kind of whitespace breakage on the corresponding
old line and want to say "Ah, those breakages are there but they
were inherited from the original, so let's not touch them for now."

Traditionally, we only had emit_add_line() helper, which knows how
to find and paint whitespace breakages on the given line, because we
only care about whitespace breakages introduced in new lines. The
context lines and old (i.e. deleted) lines are emitted with a
simpler emit_line_0() that paints the entire line in plain or old
colors.
Identify callers of emit_line_0() that show deleted lines and
context lines, have them call new helpers, emit_del_line() and
emit_context_line(), so that we can later tweak what is done to
these two classes of lines.

We have prepended $GIT_EXEC_PATH and the path "git" is installed in

for almost eternity, but the original use case the latter tried to
support was semi-bogus (i.e. install git to /opt/foo/git and run it
without having /opt/foo on $PATH), and more importantly it has
become less and less relevant as Git grew more mainstream (i.e. the
users would _want_ to have it on their $PATH). Stop prepending the
path in which "git" is installed to users' $PATH, as that would
interfere the command search order people depend on (e.g. they may
not like versions of programs that are unrelated to Git in /usr/bin
and want to override them by having different ones in /usr/local/bin
and have the latter directory earlier in their $PATH).
