Well, it can get an svndiff today, but it returns that svndiff to the caller
(wrong!), rather than combining it with the local fulltext to produce the
new fulltext.

Right now, we use the RA callbacks to determine a fulltext is present (by
asking for the version URL property which corresponds to that fulltext). We
need to expand the callbacks to say "give me the fulltext that you said you
already had." When we have that callback, then we can combine the fulltext
and diff to produce a new fulltext to return to the get_file caller.

Today, we disable get_file's fetching of svndiff's by disabling the fetch of
the version URL property.
