PATCH: spelling correction

[Peter Stephenson <pws@ibmth.df.unipi.it>]

Since we can now do spelling correction of a word directly, with the
separation of completion bits into completers, it might be as well to have
a command for it... it's a sort of generic version of _complete_filename,
which is not really necessary any more.  It relies on the compconfig
settings used in _correct/_approximate for most things, but apart from
correct_accept I couldn't think of any to set specially here.  (I can
imagine binding this to \e$.  In fact, it's hard to imagine why I'd want to
use spell-word instead.)
