blame: handle --no-abbrev
You can already ask blame for full sha1s with "-l" or with
"--abbrev=40". But for consistency with other parts of Git,
we should support "--no-abbrev".
Worse, blame already accepts --no-abbrev, but it's totally
broken. When we see --no-abbrev, the abbrev variable is set
to 0, which is then used as a printf precision. For regular
sha1s, that means we print nothing at all (which is very
wrong). For boundary commits we decrement it to "-1", which
printf interprets as "no limit" (which is almost correct,
except it misses the 39-length magic explained in the
previous commit).
Let's detect --no-abbrev and behave as if --abbrev=40 was
given.
