Perhaps I'm misreading the manpage, but I think this is wrong:
% mkdir base; cd base
% git init
% mkdir -p sub1/sub2
% cd sub1
% echo foo > .gitignore; echo '!sub2/foo' >> .gitignore
% touch sub2/foo
% git add sub2/foo
The following paths are ignored by one of your .gitignore files:
sub1/sub2/foo
Use -f if you really want to add them.
fatal: no files added
So sub1/sub2/foo matches the first pattern in sub1/.gitignore, but it
also matches the negated pattern '!sub2/foo' (in the same file, so
precedence isn't an issue). And the manpage says
o An optional prefix ! which negates the pattern; any matching
file excluded by a previous pattern will become included
again. If a negated pattern matches, this will override
lower precedence patterns sources.
So surely sub1/sub2/foo ought to be included again? Or is the first
line in sub1/.gitignore not "a previous pattern" in this sense?
If I move the "foo" pattern up a level, creating a .gitignore in base
just containing "foo", then sub1/sub2/foo is still regarded as
ignored, even though it surely matches the negating pattern
sub1/.gitignore, and that should be of higher precedence than the
pattern in base/.gitignore?
