HCI_EMPTY is *by far* the most frequent state to occur I think
(users won't press keys all the time), thus it's probably better(?)
for branch prediction to have this placed first, right?
Not that it matters too much instruction-wise, but still...

Apart from that I'm very happy to see progress on this front
(speaking as a "proud" owner of an old Toshiba notebook requiring
this stuff).

Oh, and maybe merge the sprintf()s into a single one to reduce code size.

And I'd definitely move the multiple identical "Re-enabled hotkeys" parts
into one single non-inlined(!) function for the same reason.
Not to mention that it's BUTT UGLY to have the *same* fat
multi-line comment duplicated bazillion times.

Thanks a lot!
