The documentation describes an ``escape'' character syntax, which strips
the subsequent character of special syntactic significance.  Problem is,
one would like an escaped character to be treated as an ordinary
``word'' character, so that fill commands do not wreck havoc.  E.g.,
``A\ B'' should be treated as a single word if ``\'' is an escape
character.  Unfortunately, this appears not to be the case.

I suspect it's a judgment call whether this should be the definition of
standard escape, but some ``escape-to-word-character'' syntax is merited.
