Hah. You may laugh, but talking about mis-communication, you're definitely right.
In my former saying "there are *foo-named files in current dir", I
didn't mean that I had files like:
but files named like *foo (IOW, maching the pattern *foo), id est:
(my use of "-named" was confusing obviously)
thus, from `ls *foo<TAB>` I was expecting:
I well know that to match "1.foo-named", I should use `ls *foo*<TAB>`
(trailing *) and I'm sure that you know that `ls *foo<TAB>` matches

I think we did now understand each other? ;-) to me, the subject is
over, I've did `complete -r` and voila.
