Some vim support for IN files

What's an IN file?

Eh, it's just a file with an outline. Name it foo.in. It's "in" as in inbox — a place to keep todo lists or anything else. My IN.in once had almost 7000 items! Crap! (It's down to 3000 now, but hey, at least I know this plugin is performant.)

Outlines look like:

- This item is at the top
- Here's another item
    - Items nest and stuff
        - They can nest a lot.
    - Items can be really really long, so that they wrap over multiple
      lines. I've set vim options that make this happen automatically, for
      the most part.
    - baz

What's this plugin do?

Well, it used to do lots of questionably useful things! Now I've rebooted it, and it:

• Sets some good options
• Makes <cr> act sort of clever. Maybe too clever? Hopefully intuitive.
• o and O also kinda do the right thing.

Recommendations

• Keep items formatted with judicious use of gq.
• Be careful moving items around. There's no notion of an "item" text object, so you have to do everything linewise at best.
• Use the shift operators! >> and << in Normal mode, and <c-t> and <c-d> in Insert mode. It's fun.
• Try using insort (from chreekat/usort) for sorting top-level items.
• vim-unimpaired's "paste and indent" mappings are nice. I re-implemented them like so:

  function! VimrcIndentPaste(reg, dent, dir)
      set nofoldenable
      exec 'normal "' . a:reg . ']' . a:dir . a:dent . "']"
      set foldenable
  endfu
  
  for dent in ['>','<']
      for dire in ['p','P']
          exec 'nnoremap ' . dent . dire . " :call VimrcIndentPaste(v:register, '".dent."', '".dire."')<cr>zv"
      endfor
  endfor
  unlet dire dent

  • From my vimrc
• Works well with Goyo and NrrwRgn.

I'd like to make formatting and moving easier in the future.
