Right.

Actually, we can do simpler: we still have the original line available,
so if we don't find a sha1, we can just keep it. By just letting the few
lines after the if enter the if, it just works:
strbuf_trim(split[1]);
if (!get_sha1(split[1]->buf, sha1)) {
abbrev = find_unique_abbrev(sha1, DEFAULT_ABBREV);
strbuf_reset(split[1]);
strbuf_addf(split[1], "%s ", abbrev);
strbuf_reset(line);
for (i = 0; split[i]; i++)
strbuf_addf(line, "%s", split[i]->buf);
}

I took this (modulo s/line.len[0]/line.buf[0]/, and s/rtrim/trim/ to be
robust to leading whitespace (not really important, but doesn't harm).
