You can write your own function.  See Functions/multicomp in the
source distribution for examples.  If you really can't type uppercase
characters, you're going to have to redo the globbing there so
that every lowercase character becomes e.g. [rR], then you'll
need to handle .'s in the way /'s are handled there.  Ignoring case
may happen one day, but I doubt there's ever going to be a built-in
way of saying 'look and see if there are any characters preceeding a
dot to be added earlier on in the completion'.  Maybe you would be
interested in the options automenu and menucomplete.  You'll have
to find the shift key, however.  Do 'setopt automenu', type R,
and hit tab until it works.

You need ls -d, and it doesn't just show empty directories since the link
count doesn't get incremented for plain files.  I don't think you
can do it in one glob expression.  Best I can think of (using your
glob to prune out non-terminal directories) is

for f in ***/*(/l2); do foo=($f/*(N)); [[ -z $foo ]] && print $f; done

*(N) turns on nullglob, i.e. $foo is empty if there was nothing in $f.

This should happen with the option CHASE_LINKS unset.

With 3.1.4, -/ is a better way of doing it than -g; this will work as you
want.  For more general things like that, you probably need to wait
until particular completions can be bound to particular keys, which
should happen some time.
