For backends calling processes in order to check `vc-registered', it
doesn't optimize. But for other backends, like cvs or svn, which do not
call processes, it is *really* a performance boost.
IIRC, it was recommended by a Tramp user running svn. If you're
interested, I could try to find old messages comparing performance
numbers w/ and w/o this optimization. Ten years ago, I guess.
