When rsync encountered an empty file list, it behaved differently

When rsync encountered an empty file list, it behaved differently
when pulling files than when pushing files:  pulling it output a
(mostly) unhelpful error message and then exited with a 0 status,
even when the remote side exited with an error code.  I changed this
to output the normal end summary (when verbose) and to exit with the
status intact (just like when pushing files).
