Hi there
It seems that negating path patterns in gitignore doesn't work, or I
don't understand it (or both). With the attached script, git status
(1.5.5.1) reports "dir/a" as new and "dir/b" as untracked. I would
rather expect it to report "dir/c" as untracked also.
It seems that "!b" matches to include "dir/b" (reverting the
exclusion
"*" as expected), whereas "!dir/" does not match to include "dir/c".
What's going on here?
"dir/" will not match anything, because paths are compared without
trailing slashes. Try "!dir".
I am sorry, but this is plain wrong, at least if "man gitignore" is
right (see below). "!dir" would match files whose name (pathname
without leading directory name) matches "dir" (i.e.: is dir) and
exclude those from exclusion (include them).
Also, replacing "!dir/" by "!dir" in my test script does not change
the result. In fact, for "!dir" the result is as expected and
documented, just for "!dir/" I would expect something else.
So, thanks for trying to help, although reading the manual or
testing your advice before would be appreciated even more. ;)

From man gitignore:
If the pattern ends with a slash, it is removed for the purpose of
the following description, but it would only find a match with a
directory. In other words, foo/ will match a directory foo and paths
underneath it, but will not match a regular file or a symbolic link
foo (this is consistent with the way how pathspec works in general
in git).
Ahh, the behavior changed in 1.5.5. Pre-1.5.5, if a path ended in a
slash, it would never match anything.
In any case, the problem is the * pattern. Here's what happens:
At /, the * is evaluated and ignores everything. The !dir/ is
evaluated and unignores dir. The !b is evaluated and matches nothing.
AT /dir, the * is evaluated and ignores everything. The !dir/ is
evaluated and matches nothing. The !b is evaluated and unignores b.
So the problem is the * is recursively applying to the subdirectories.
To fix this, use /* as the pattern.
