:-) Our research and development department is working with high
pressure. Once the problem was found the quick fix was the first iteration.

We tested this internally with FILO which makes heavy use of
CTRL-sequences and cursor keys, and I am confident that the merged
driver is the way to go. It does a good job here, and if further bugs
might appear, it will make things easier because we only need to fix
them in one place.

Though it reduces the code, it makes the keyboard lookup tables bigger
since we have to store shorts instead of chars for that for each character.

I vote in favor of dropping my first patch and use Patricks much better
version.
