See [PATCH] gitweb: fix commitdiff for root commits from Jakub:
> No checking for empty $hash_parent in git_commitdiff_plain -- we
> rely on gitweb to give correct parameters for commitdiff_plain
> action.
I think we should always check the input and prevent any warnings.
This patch is on top of Jakubs patch, mine just did the if (!($line =~
m/..)) { next; } to be consistent with the other ifs.
