This with list-dirs-first has one issue:

$ ls u/s*/ax	-- cursor over 'a', tab menu cycling

[directories]
usr/share/aclocal/ x
usr/share/atever/ x
[files]
usr/sbin/a1
usr/share/a1
usr/share/a2

Note missing ' x' after completing files. Is that -U dropping the SUFFIX?

This cycling (ctrl-g toggling of behaviour) means something is not being
reset/unset properly and should be fixed.

However the latter case:

> $ ls a/b/d/e/g[tab]
> $ ls a/b1/d/e1//g
> b1/d/e1/  b1/d/e2/  b2/d/e1/  b2/d/e2/

with cursor over first of "//" also differs from the first run (the
correct one).


This is caused by MBEGIN and MEND variables being set in both cases
(add-space and not). If they are about to be kept between the completion
invocations (even after the ctrl-c), they should not be used in
completion functions. Otherwise they should be cleared not to leak some
bogus state into consecutive invocations.

What is the purpose of MBEGIN and MEND?
