After a bugreport for RHIDE I found that also the
getkey() and getxkey() functions are buggy. They do
not report the correct value for the character with
the code 224(0xe0).

That means, any program that uses that functions, cannot
use that character (to type it in use the Alt + numpad
code technique). I don't know what programs all affected
by this but it is at least also bash.

BTW: The ASCII 224 is the greek alpha.

Here are now the patches for both functions:
