git-diff/git-apply: make diff output a bit friendlier to GNU patch (part 1)
Somebody was wondering on #git channel why a git generated diff does not apply with GNU patch when the filename contains a SP. It is because GNU patch expects to find TAB (and trailing timestamp) on ---/+++ (old_name and new_name) lines after the filenames. The "diff --git" output format was carefully designed to be compatible with GNU patch where it can, but whitespace characters were always a pain. We can make our output a bit more GNU patch friendly by adding an extra TAB (but not trailing timestamp) to old/new name lines when the filename as a SP in it. This updates git-apply to prepare ourselves to accept such a patch, but we still do not generate output that is patch friendly yet. That change needs to wait until everybody has this change. When a filename contains a real tab, "diff --git" format always c-quotes it as discussed on the list with GNU patch maintainer previously: http://marc.theaimsgroup.com/?l=git&m=112927316408690&w=2 so there should be no downside.
