[PATCH] gitk: Add workaround to handle corrupted author date

[Steffen Prohaska <prohaska@zib.de>]

6e6db85ea9423eea755cf5acf7a563c0d9559063 contains a corrupted
author line, which is lacking the time and timezone information.

This commit adds a workaround to handle this situation.  If the
time cannot be parsed, it is assumed to be 0 and the full line
is assumed to be the author's name.

This works around the issue for me.  However, I don't think
this patch should be applied.

The best was if such a corrupted commit wouldn't enter the
repository in the first place.  But once it is there, I think git
should verify the format of a commit and report an approriate
error.  gitk could continue to assume well formed commits.
