Since we are nitpicking, I think:
static int needs_from_quoting(enum cmit_fmt fmt,
const char *line, size_t len)
{
if (fmt == CMIT_FMT_MBOXRD && is_mboxrd_from(line, linelen))
return 1;
if (fmt == CMIT_FMT_EMAIL && is_from_line(line, linelen))
return 1;
return 0;
}
...
if (needs_from_quoting(pp->fmt, line, linelen))
strbuf_addch(sb, '>');
is even nicer. There are lots of alternatives to write the helper
function, and I do not care much which one is chosen. But splitting it
out into a concise "do we need to do this?" query function makes the
flow in pp_remainder much easier to follow.
