Fix "git log -z" behaviour
For commit messages, we should really put the "line_termination" when we output the character in between different commits, *not* between the commit and the diff. The diff goes hand-in-hand with the commit, it shouldn't be separated from it with the termination character. So this: - uses the termination character for true inter-commit spacing - uses a regular newline between the commit log and the diff We had it the other way around. 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". By fixing "git log -z", you can now also do insane things like git log -p -z | grep -z "some patch expression" | tr '\0' '\n' | less -S and you will see only those commits that have the "some patch expression" in their commit message _or_ their patches. (This is slightly different from 'git log -S"some patch expression"', since the latter requires the expression to literally *change* in the patch, while the "git log -p -z | grep .." approach will see it if it's just an unchanged _part_ of the patch context) Of course, if you actually do something like the above, you're probably insane, but hey, it works! Try the above command line for a demonstration (of course, you need to change the "some patch expression" to be something relevant). The old behaviour of "git log -p -z" was useless (and got things completely wrong for log entries without patches).
