In the process of a blame operation, the server is already performing
binary deltas (which aren't directly usable for blame) between each pair
of revs. It wouldn't necessarily be any more work for the server to
perform line-based diffs instead, although that would be the sort of
text processing we don't ordinarily put into the server code.

Alternatively, the server could perform a more diff-like binary delta,
where the only instructions are "copy the next N bytes from the input"
or "insert these new bytes." Such a binary delta could possibly be
transformed into line-based diffs on the client, although I'm not
completely sure of that.
