This seems to fix `comint-arguments' but there is still the problem
that `comint-delim-arg' splits further on backslash quoted special
characters (in this case the parens).

I'm a bit lost now.  I have no idea if it breaks one of the several
comint based modes if we don't split at quoted special characters
here.  I suspect it would make sense to add some extra buffer local
variable which defines the quote characters.
