Hi Dimitry,

Thanks for taking a look.

The result seems as designed.  I expected something different.

Probably not.

The variations here seem be the same as the MUSTMATCH parameter to
read-file-name.  I had tested those and none of those seem to do what I
want.

It's not like I do not like completion in general, but for me and in
this situation I want it only on-demand (with TAB), not automatic and
with almost no feedback about the choice that was actually made.

I may just learn my lesson here for now, but I'm not sure this is good.
Also I wanted to hear if anybody has a tip about some customization that
I was missing.
