I'm not quite sure what a mini-window is.  Does it mean the window within
which the minibuffer is displayed?  As in max-mini-window-height?

Perhaps.  If we can formulate the two (or several) options in a
non-confusing way.  This is a fairly arcane matter.

My apologies for being unclear.  I was thinking about what happens after
the Isearch is over.  Currently the minibuffer is pulled in if the
Isearch has used the minibuffer for any reason.  With my patch, this
would never happen after an Isearch.

What I meant was that with the "always" variation, after an Isearch, an
open minibuffer would always be pulled over from another frame.
