- fix known bugs and known todos!
- esc is a little slow as ins->cmd mode key
- 3"ap doesn't work but "a3p does

- :imap
- custom scripts (vim-like functions) which can be mapped
    - surroundings, with an external script if somebody writes it

            # Ignore invalid operator/char combinations.
            #} elsif ($operator and ($char eq 'j' or $char eq 'k')) {

- support :map gX iINSERT TEXT<ESC> and similar stuff (suggested by estragib)
- it would be nice if :ls somehow indicated current and alternate buffer
  (maybe activity too?) (suggested by estragib)
- < estragib> oh, i can't map \<something> either
  < estragib> hehe, definitely something to do with escaping. \\ prints \
- < estragib> there's a minimal difference to vim when yanking with yB:
              abc def ghi jkl<ESC>bhyBP
  < estragib> vim     : abc def ghighi jkl
  < estragib> vim-mode: abc def ghi ghi jkl
