#8 problem with new keyb_getkey()

[asdf]

Functions like gets() which call keyb_getkey() don't seem to work properly. The key in the rightmost column (backspace, U, Z, *, -, +, and enter) is always returned.

Part of the problem seems to be that the routine to decode rowData was moved for the hpgcc 2.0 release. Fixing this allows the calculator to read in numbers correctly, but there are still problems with letters.
