A little oversight in the test in `ctokenize()'.

That one is a poser... `expand-or-complete' never expanded this
without braces. If it expanded it, it wouldn't add a trailing slash
(but instead add a space, try `${PWD:h}<TAB>'). So this is handled by
the completion code. There, it expands the `$PWD:h', gets a path from
it, and then tries to complete the last pathname component. So I think 
the best solution would be to add a slash (and leave the line
otherwise untouched). BUT I have no idea how I can get the code to do
this... The problem is that after expansion, the code can't find out
what came from the expansion in cases like `${foo}x<TAB>'. So the
patch just uses the expanded prefix if it has the problem that the
expanded prefix contains slashes and the original string doesn't.
Maybe a better solution would be to do nothing in such cases.

The patch also contains a small cleanup in `acceptandmenucomplete()',
making `iremovesuffix()' be called when no brace expansion prefix was
collected.
