If you swap a60ea8f and bac65a2 so that we can have tracing even
without the problematic commit a60ea8f (dir.c: fix match_pathname() -
2016-02-15). Without a60ea8f I got
GIT_TRACE_EXCLUDE=1 ~/w/git/temp/git status -suall 2>&1 >/dev/null
|grep waldo
07:25:05.639445 dir.c:952 exclude: baz/waldo.txt vs * at
line 1 => yes
(meaning, baz/waldo.txt matches "*" rule and is decided to be excluded)
with a60ea8f

the decision is not taken earlier from line "!/baz" and it's decided
to be re-included. Which I would argue is the correct thing because
you ask to re-include the whole directory "baz". It should behave this
way because exclude rules without '!' behave this way.
Because positive any negative rules can be nested, by adding a rule to
reinclude what's inside baz..
*
!/foo
!/foo/bar.txt
!/baz
/baz/*
!/baz/quux
!/baz/quux/**/*
you'll get baz/waldo.txt excluded.
Yes it's a behavior change. I think the old behavior is unintended.
But it's probably out there long enough that many .gitignore files may
rely on it and by making it right, I break them. Whether to revert the
series is up to you. Let me know if I should send the revert patch.
