Point taken.

Perhaps it would be better to hand delta windows to the caller, as
originally theorized. As has been pointed out, some day it may be
possible to do something clever to calculate diffs from delta windows
(although that sounds awfully hard and not very rewarding), and
generally our RA interfaces match pretty closely the kind of data being
passed over the wire, even over HTTP.

A helper function in libsvn_client/blame.c can translate the delta
windows to temporary files.
