Things are already broken, slightly.

In my recent enhancements to the minibuffer handling, I noticed that
minibuffers (the actual buffers) began life in fundamental-mode, got
used, then on termination were put into minibuffer-inactive-mode.
However, on being reused, these buffers remained in
minibuffer-inactive-mode rather than being restored to fundamental-mode.
This is silly, and "obviously" a bug. I fixed this bug by making an
active minibuffer always be in fundamental-mode.

An active minibuffer doesn't use its own key map - it uses the key map
supplied to it by the calling function. This is how being in
minibuffer-inactive-mode (which does have its own key map) "worked" for
so long.

The OP of this bug tells me that minor modes which maintain lists of
"valid" major modes they work in, included minibuffers by including
minibuffer-inactive-mode in their lists. This sort of worked (except for
the first time a minibuffer was used), but is undesirable.
So the idea is to allow these minor modes to specify minibuffer-mode.

I think there's a bug here, yes. I don't know of any particular minor
mode, off hand, that is affected by this, but the OP assure me they
exist. This isn't really the sort of bug that has recipes.

No apology needed! Thanks for raising the points.
