Scrollbar management in the minibuffer window might be unpredictable.
Also, GTK builds usually hide the scroll bar in a one line minibuffer
window automatically, so even the 'min-slider-length' might come into
play here.
To make sure we don't miss anything before proceeding further:
(1) Is this behavior special for the minibuffer window? That is, if
in 'after-make-frame-functions' you removed the scroll bar from any
other window, does it stay removed when you switch to that window
repeatedly?
(2) Does showing a message in the echo area suffice to make the scroll
bar reappear? With other words, what does "use" the minibuffer stand
for?
(3) I suppose "it isn't removed afterwards" means you can still remove
the scroll bar explicitly via 'set-window-scroll-bars' afterwards.
Right? And if you do that, does it come back after yet another "use"
of the minibuffer?
(4) Can you influence the behavior by customizing the variable
`resize-mini-windows'?
Thanks, martin
