[PATCH 0/2] infinite loop in "git ls-tree" for broken symlink

[Petr Stodulka <pstodulk@redhat.com>]

Hi,
I have realized that this wasn't fixed after all when refs.c
was "rewritten". Issue is caused by broken symlink under refs/heads,
which causes infinite loop for "git ls-tree" command. It was replied
earlier [0] and Michael previously fixed that in better way probably,
then my proposed patch 2/2, but it contains more changes and I have not
enough time to study changes in refs* code, so I propose now just my
little patch, which was previously modified by Michael.

If you prefer different solution, I am ok with this. It is really
just quick proposal. Patch 1/2 contains test for this issue. If you
will prefer different solution with different exit code, test should
be corrected. Basic idea is, that timeout should'n expire with
exit code 124.
