then use `find ...`, problem solved.

btw if your requirements are this stringent you would have done well
if you laid them out upfront.

it's not, at least all BSDs have it as well.  again, what operating
systems do you need to support?

you can `find . -maxdepth 1 -mindepth 1`, but the paths will be prefixed
with "./".  you could of ocurse append `| sed 's:..::'`.

OTOH, what's the problem with the shell expanding the globs?
if .* or * does not exist, sh leaves that there as-is, find cannot
chdir into it, and definitely won't print it.

yeah, that was a brainfart, sorry.
