I can try to help writing tests for lib/ utf-8 stuff, and I am sure
there is lot of things to do there to do for Andrew also. Anyway there
is ton of corner cases.

I would also like to know if there would be anyway to do automated
testing for VI, ofc I could do it by implementing ex command
substitute for every visual mode command and then implement -c option
with multiple commands in row parsing. But I feel that implementing ex
commands just for testing purposes is bit tedious. And I am not sure
if there is visual mode commands that does not have ex mode
substitute. So if there would be easy way to push "interactive"
command slowly like "5G3dd:wq\n" and then check diff if 3 lines are
missing after line 5 or not...
