Yes, the problem is in comint-arguments which attempts to parse a shell
line into separate arguments, using just a bunch of regexps.  This is
doomed to failure I think.  But the alternative would be a full blown
shell parser, so I don't know how feasible it will be to fix this bug.
It's been with us a long time.
