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.
Not every 3-line function needs to be a primitive. What does it do

Quoting the whole defun, especially including the docstring, would
probably be the best idea.
