vc-annotate and SCCS

[skip at pobox.com]

I use vc (both the old at work and Ville's new version at home).  I
occasionally annotate files in our CVS repository ("who's to blame for that
boneheaded mistake?" - usually me ;-), but we have a few files which are
still in SCCS.  As far as I know SCCS doesn't have any sort of annotate
command.  When I execute vc-annotate on an SCCS-managed file it responds

    File /x/y/z is not under version control

That's almost certainly the wrong error message.  I can check the file out,
check it back in, etc.

This is the old vc (whatever comes with 21.5.28), not the new.  I actually
don't have any SCCS files at home to try this out with.  If necessary, I
will set something up.
