I don't know.  And I don't have time right now to track it down.
But I'll try to take a look later some time.

No, absolutely not.

I didn't start typing.  In Icicles it often makes sense to show
all initial completions from the outset, either automatically or
on demand.

While waiting for better understanding of the problem, and
possibly a fix if there is in fact a bug and solution, I will
automatically turn off `icomplete-show-matches-on-no-input'
when Icicle mode is turned on.

BTW, there is no such problem with using IswitchB with Icicles,
AFAIK.
