bug#7378: 23.2; grep buffer misinterprets result if filename contains colon character

AFAIK we do try to figure out what was meant, even though in general
grep's output is simply ambiguous when the file name has colons.

So, could you give the exact file name you used, so we can try and
figure out whether it's a bug in the current heuristic, or it's
a hopeless case (it's just too ambiguous), or it's a case that's simply
not yet handled.
