looking-back - looking-at

[Andreas Röhler]

AFAIS `looking-back' as pendant to `looking-at' is not
available at XEmacs. Would like to have it for
compatibility reasons, should I'm being right so far.

GNU/FSF `looking-back' went without difficulties on 
XEmacs 21.5  (beta27) "fiddleheads" (+CVS-20060704) [Lucid] 
(i386-suse-linux, Mule) of Mon Nov 27 2006 on dale, so maybe
copying is enough?

Thanks
