On the log-message-templates branch, fix mishandling of relative or
unversioned paths in the commit target list.

* subversion/libsvn_client/commit_util.c
  (svn_client_get_log_message_templates): Make paths absolute before handing
   them off to svn_client_propget5(), else we'll run into an assert.
   If an unversioned path in the commit target list is found, which
   will happen during 'svn import', just skip it instead of erroring out.
