[PATCH 0/3] fix "git add" pattern matching

[Clemens Buchacher <drizzd@aon.at>]

Hi,

Johannes Schneider reported that "git add '*'" did not add matching files.
And indeed pattern matching for tracked files is broken since 1.6.1. I've
never used this feature myself, but I can imagine it's useful in some
situations. For example, you can do "git add '*.c'" to add all .c files. The
equivalent command without pattern matching would be
"find .  -name '*.c' | xargs git add".

[PATCH 1/3] clean up pathspec matching
[PATCH 2/3] remove pathspec_match, use match_pathspec instead
[PATCH 3/3] implement pattern matching in ce_path_match

This patch series fixes pattern matching for "git add". The first two
patches are cleanups only. PATCH 3/3 then implements pattern matching in
ce_path_match. It is very intrusive in the sense that all commands using
ce_path_match will now have pattern matching. I suppose this is good in
general, but can also have undesired side-effects, as in "git log --follow
'*'", for example. I'd appreciate some double-checking in that context.

Cheers,
Clemens
