Meh, that's probably going too far in the direction of imprecision.
The point of this patch is that only very specific errors are
suppressed.

I don't have a better idea though.  It'd be easier if there were
separate switches for the two cases, then you could call them
--ok-if-running and --ok-if-stopped.  But that's not very workable,
if only because both would want the same single-letter abbreviation.
