git-svn: fix output reporting from the delta fetcher

There was nothing printed in the code originally because I left
out a pair of parentheses.  Nevertheless, the affected code has
been replaced with a more efficient version that respects the -q
flag as well as requiring less bandwidth.

We save some bandwidth by not requesting changed paths
information when calling get_log() since we're using the delta
fetcher.
