Improve the input a lot

Noticeable changes:

- The input "view" is smarter, it always move to a decent position so we can
  see enough text around the cursor.
- The cursor goes at the end of the input when pasting some long text
- The formatting chars (^C and o, b, a, 1, 2, 3 etc) are now visible in the
  input. This makes it a lot easier to know where these special characters
  are, to change them and efficiently edit our text (we just lose a little,
  on the cosmetic side, but who cares)
- The code is actually a lot simpler in the functions to move the cursor,
  insert/delete chars: we do not have to deal with special cases where the
  formatting characters are actually composed of two chars.

fixes #2183
