... or so with would seem :-)  But if the user customizes
`icomplete-show-matches-on-no-input` to t, the problem is
there again.

fido-mode's ido-opinionated semantics automatically turn
on that variable during fido-completion and that's why you
get the error unconditionally in fido-mode.

The error was introduced by me, anyway, in both modes,
and the fix is simple.  It'll be in emacs-27 in a moment.
