vi: fix buffer overrun; code shrink
It was possible for get_input_line() to store its NUL terminator
one character beyond the end of its buffer.
Code shrink in colon():
- Certain colon commands can be matched exactly, as any shorter
string would be matched earlier, e.g. ':wq' versus ':write'.
- Command matching is now case sensitive so there's no need to
check for 'N' or 'Q' suffixes.
- Rewrite how commands and arguments are split.
