Makes sense.

I think the information you want has been thrown away by the time we get
to grep_object. Only get_sha1 knows whether the name was really a direct
tree reference or if it had to traverse paths.
So we are necessarily reconstructing based on what we know of the
syntax. And I think that your rule is OK, because we know that refnames
cannot contain a colon. So even though pathnames can, we do not have to
care; we only want to know "is there a path in the name", and if we have
at least one colon, the answer is yes.

A test would be nice. Both to make sure we do not re-break it, and because
it helps demonstrate the problem very easily (it took me a minute to
figure out what was going on from your description).

Please use whitespace with your ternary operator. The '/':':' made me
think I was reading Perl for a minute. :)
