bug#14661: 24.3.50; `C-<scroll>' is seen as `C-<pause>'

[Drew Adams]

Dunno whether this is an Emacs bug or a keyboard problem.

When I use `C-h k' and then press Control and hit the Scroll Lock key,
Emacs takes that as `C-<pause>', not `C-<scroll>'.  However, every other
combination of a modifier with the Scroll Lock key, and use of no
modifier with it, acts as I would expect: Emacs sees
`<scroll>',`M-<scroll>', `C-M-<scroll>', `C-S-<scroll>', `S-<scroll>',
`M-S-<scroll>', and `C-M-S-<scroll>'.
