Why is textwidth not used for soft wrap? about vim-pencil HOT 2 CLOSED

It seems that the reason is that vim does not support soft wrapping at a set text width. See the discussion at https://stackoverflow.com/questions/989093/soft-wrap-at-80-characters-in-vim-in-window-of-arbitrary-width and neovim/neovim#4386

I agree that soft wrapping at textwidth would be very useful and it is bizarre to me that vim doesn't support it.

This issue is pretty much held-up by upstream implementation. I don't think Pencil can do anything about it. A poor-man fix is described in the SO question linked above:

set columns=80
autocmd VimResized * if (&columns > 80) | set columns=80 | endif

...but that will only work for some terminal situations. It works with Neovim inside tmux inside Termite, but will probably mess with your window in many Terminals. When upstream VIM or Neovim supports this it will naturally also filter down to Pencil users.

If anybody is extra eger for this I would suggest sponsoring a bounty on the Neovim issue (Bountysource was supported last I checked).
