In 51667147be, "git apply --whitespace=fix" was extended to
allow a blank context line to match beyond the end of the file,
but only if the context line was in the leading part of the
hunk (i.e. the hunk inserted additional contents at the end
of the file).
Drop the restriction that the context line must be in the
leading part of the hunk, thus allowing a file to be changed
from:
a
(blank line)
to:
b
a
(blank line)
Note that the blank line will be kept, because "--whitespace=fix"
only removes trailing blank lines that a hunk would add, never
trailing blank lines in the context.

The command "git rebase --whitespace=fix HEAD~<N>" is supposed to
only clean up trailing whitespace, and the expectation is that it
cannot fail.
Unfortunately, if one commit adds a blank line at the end of a file
and a subsequent commit adds more non-blank lines after the blank
line, "git apply" (used indirectly by "git rebase") will fail to apply
the patch of the second commit.

"git apply --whitespace=fix" will not always succeed when used
on a series of patches in the following circumstances:
* One patch adds a blank line at the end of a file. (Since
--whitespace=fix is used, the blank line will *not* be added.)
* The next patch adds non-blank lines after the blank line
introduced in the first patch. That patch will not apply
because the blank line that is expected to be found at end
of the file is no longer there.
A patch series that starts by deleting lines at the end
will fail in a similar way.
Fix this problem by allowing a blank context line at the beginning
of a hunk to match if parts of it falls beyond end of the file.
We still require that at least one non-blank context line match
before the end of the file.
If the --ignore-space-change option is given (as well as the
--whitespace=fix option), blank context lines falling beyond the end
of the file will be copied unchanged to the target file (i.e. they
will have the same line terminators and extra spaces will not be
removed).

In the next commit, we will make it possible for blank context
lines to match beyond the end of the file. That means that a hunk
with a preimage that has more lines than present in the file may
be possible to successfully apply. Therefore, we must remove
the quick rejection test in find_pos().
find_pos() will already work correctly without the quick
rejection test, but that might not be obvious. Therefore,
comment the test for handling out-of-range line numbers in
find_pos() and cast the "line" variable to the same (unsigned)
type as img->nr.
What are performance implications of removing the quick
rejection test?
It can only help "git apply" to reject a patch faster. For example,
if I have a file with one million lines and a patch that removes
slightly more than 50 percent of the lines and try to apply that
patch twice, the second attempt will fail slightly faster
with the test than without (based on actual measurements).
However, there is the pathological case of a patch with many
more context lines than the default three, and applying that patch
using "git apply -C1". Without the rejection test, the running
time will be roughly proportional to the number of context lines
times the size of the file. That could be handled by writing
a more complicated rejection test (it would have to count the
number of blanks at the end of the preimage), but I don't find
that worth doing until there is a real-world use case that
would benfit from it.
It would be possible to keep the quick rejection test if
--whitespace=fix is not given, but I don't like that from
a testing point of view.

In match_fragment(), the line lengths in the preimage are updated
just before calling update_pre_post_images(). That is not
necessary, since update_pre_post_images() itself will

When 921177f (Documentation: improve "add", "pull" and "format-patch"
examples, 2008-05-07) converted this from enumeration header to displayed
text, it failed to adjust for the AsciiDoc's rule to quote backslashes.
In displayed text, backslash is shown verbatim, while in enumeration
header, we need to double it.
We have a similar construct in git-rm.txt documentation, and need to be
careful when somebody wants to update it to match the style of the "git

That commit made the situation better for repositories with relatively
small number of objects. However with many objects and a small pack size
limit, the time required to complete the repack tends towards O(n^2),
or even much worse with long delta chains.

The code to guess an output archive's format consumed any --format
options and built a new one. Jonathan noticed that it does so in an
unsafe way, risking to overflow the static buffer fmt_opt.
Change the code to keep the existing --format options intact and to only
add a new one if a format could be guessed based on the output file name.
The new option is added as the first one, allowing the existing ones to
overrule it, i.e. explicit --format options given on the command line win
over format guesses, as before.
To simplify the code further, format_from_name() is changed to return the
full --format option, thus no potentially dangerous sprintf() calls are
needed any more.

This function did not work on strings that were not NUL-terminated. It
reads through a length-bounded string, searching for characters in need of
quoting. After we find one, we output the quoted character, then advance
our pointer to find the next one. However, we never decremented the
length, meaning we ended up looking at whatever random junk was stored
after the string.
This bug was not found by the existing tests because most code paths feed
a NUL-terminated string. The notable exception is a directory name being
fed by ls-tree.

Revert the previous attempt to skip this test on platforms where we
currently cannot determine the system load. We want to make sure that
the max-load-limit codepath produces results cleanly, when gitweb is
updated and becomes capable of reading the load average by some other
method.
The code to check for load returns 0 if it doesn't know how to find
load. It also checks to see if the current load is higher than the
max load. So to force the script to quit early by setting the maxload
variable negative which should work for systems where we can detect
load (which should be a positive number) and systems where we can't
(where detected load is 0)
