commit f75f90a5ddb5e282594483dd7b5dae36f94794c3
Author: Peter Oliver <address@hidden>
Commit: Lars Ingebrigtsen <address@hidden>

    Allow vc-sccs-diff to work with TRAMP
    
    * lisp/vc/vc-sccs.el (vc-sccs-diff): If the diff command is to be
    run remotely, then the temporary files it's acting on must be
    remote too (bug#37777).
