The original logic was (best seen with git show -w 660e113):
if(showing graphs) {
do pretty things
}
else {
just print the buffer and the header terminator
}
660e113 changed that to
do pretty things
Given that the 'do pretty things part' works for other uses of git rev-
list, it made sense that the \0 should only be added back in
CMIT_FMT_RAW mode. Changing the first putchar('\n') as Jacob proposes
(that mail arrived while I'm typing this) might work too, I haven't
tested it.
