range-diff: suppress line count in outer diff

The line count in the outer diff's hunk headers of a range diff is not
all that interesting.  It merely shows how far along the inner diff
are on both sides.  That number is of no use for human readers, and
range-diffs are not meant to be machine readable.

In a subsequent commit we're going to add some more contextual
information such as the filename corresponding to the diff to the hunk
headers.  Remove the unnecessary information, and just keep the "@@"
to indicate that a new hunk of the outer diff is starting.
