[PATCH] debugger (step backwards)
Message ID:
Patch for the debugger to enable stepping backwards.

Stepping backwards is made possible by using a true history (earlier save 
command), and rerunning the debugger to the indicated command, or to so-many 
steps backwards, or to the current position.  

I've used 'rerun [[-]n]' as the command (h rerun) so as not to upset anyone 
with backward compatibility with the R command.  Interestingly, it works 
quite well.

The patch includes an update to the pod pages we accept (as man/doc), and some 
final whitespace clean up, and should apply to both 5.8.x and 5.9.x versions, 
(which should currently be identical, after the recent unforking episode).
