This also fixes a more common case: an abbreviated ID that collides only
with trees or blobs used to fail unless a subject was given. 117 of the
last 2000 commits in linux.git have a 7 character abbreviation like that.

The argument check at the bottom of the script still counts every object
type, so a prefix that matches only a blob now exits 1 without printing
the "does not match any git commit" error. Could you send a follow-up
that filters that check the same way?
