The SKIP verb don't need backtracking after it fires: there is bumpalong
and new match. If MARK position is saved then there is no problem for
engine to discard current matching and start new matching at saved
position without any backtracking. Isn't it?
So may be not impossibility of backtracking into atomic group is the
reason of current behavior. May be Perl compatibility is it?
