Let's rein in the hyperbole.  Bash uses DEL as an internal marker character
during word expansion, so problems involving DEL are a higher priority than
you might think.  I apologize for not testing the corner case you ran
across, but it's been 18 months since the patch was released and yours is
the first report of problems with it, so it doesn't seem to have affected
many people.

I am working on getting bash-4.3 out the door before I think about
releasing additional patches to bash-4.2.  I have appended something you
can apply -- your line numbers will certainly vary -- to get you past the
problem you're currently having.
