Subject: Fast-forwarding does a git.switch() even when it forwarded no patches
X-Git-Tag: v0.14.3~568

Fast-forwarding does a git.switch() even when it forwarded no patches

The git.switch() in forward_patches() is not needed when no patches have
been fast forwarded.  This is a significant speed up.
