bug#12806: 24.3.50; Dead keys misbehavior when scroll-lock is enabled

I'll see what can I do, but FWIW, the situation now is much worse than before:
* Scroll lock is a key that is usually set "off"; that explains why no
one noticed this bug until now.
* What is more important: I've just seen that typing `C-M-u' does
nothing on Emacs.  It is as if no key was pressed at all.  If I do
`C-h c C-M-u' the minibuffer stays as if no key was pressed after `C-h
c'.


FWIW:
* This is with bzr revno 110824.
* Your commit at revno 110822 has a typo: the bug number is "12086",
but you wrote "1280".
