1.8.3 - gitignore not being parsed correctly on OS X; regex support is broken?

Hi,

Gitignore parsing no longer seems to work properly in git 1.8.3.

One of my repositories has the following gitignore:

/*
!/.gitignore
!/Library/
!/CONTRIBUTING.md
!/README.md
!/SUPPORTERS.md
!/bin
/bin/*
!/bin/brew
!/share/man/man1/brew.1
.DS_Store
/Library/LinkedKegs
/Library/PinnedKegs
/Library/Taps
/Library/Formula/.gitignore

In 1.8.2.3 and earlier, this works as expected. However, in 1.8.3 I'm
seeing every file in /bin/ being marked as an untracked file.

I asked about this in #git, and was told that the culprit was the
regex support; apparently recompiling without regex support fixes the
specific gitignore issue. However, this doesn't seem to have been
reported anywhere on the mailing list that I can see. I was also told
that the issue is OS X-specific, and doesn't happen on other
platforms.

Thanks,
