May I raise again the issue of names?  That is, could we please
consider

	back-step
	previous
	back-continue
	back-finish

?  I think ``reverse'' is ambiguous: it doesn't actually say that we
are going backwards, just that we are reversing the direction, like
some kind of toggle.  Reverse would be okay if we had some global
direction flag which ``reverse'' command would reverse.  This is not
the case: these commands will _always_ go backwards, even if we
implement exec-direction and the user sets it to `backward'.

See, you used ``backward'' here, not ``reverse''.

And here as well.  So it looks like your instincts prefer ``back'',
like mine ;-)
