Don't waste CPU time creating deltas against the empty stream; just
use a single insert operation.
The only reason to represent deltas against the empty stream as
anything other than a single insert operation would be to "compress"
it; but since most of the time we're gzipping the delta stream anyway,
this is usually a waste of time.
This does mean that more bandwidth will be used when talking to
pre-1.4 clients, and more disk space will be used when storing data in
pre-1.4.x FSFS repositories. However, by the time 1.6.0 is released,
pre-1.4.x clients will be very old, and there is an "svnadmin upgrade"
command to upgrade old repositories.
(compute_window): Replace call to svn_txdelta__vdelta with a single
call to svn_txdelta__insert_op.
