Re: Fix "git log -z" behaviour

Linus Torvalds [off-list ref] writes:

For the normal case where the termination character is '\n', this 
obviously doesn't change anything at all, since we just switched two 
identical characters around. So it's very safe - it doesn't change any 
normal usage, but it definitely fixes "git log -z".

Gaah.

I have already applied this but I think this has fallout for
existing users of "-z --raw".  Nothing in-tree uses "git log" as
the upstream of a pipe as far as I know because in-tree stuff
tend to stick to plumbing when it comes to scripting, but I
think your patch would affect the plumbing level as well.

Scripts that read from "-z --raw" have been expecting to get a
record whose first 7 bytes are "commit " to be a log, which is
followed by an arbitrary number of records whose first byte is
":" (and then it needs variable number of records to complete
one diff record).  This patch removes the separator NUL between
the log message and the first diff record.
