Then I think the correspondence of RCS commands will be Git commands 
that act similarly on the local repository.

Then 'git reset --hard HEAD^' is a better match, because, like someone 
explained, the point of 'rcs rollback' is to remove the revision in 
question from history.

And if 'git reset' is unsafe, well, 'rcs rollback' doesn't sound 
particularly safe either.

Either way, we need a smart way to detect dangerous operations (e.g. see 
if affected commits are already published). The "amend" Git capability, 
which we already support, is unsafe too.
