  * - do not store terminal window in viminfo.  Or prefix term:// ?
  * - add a character in :ls output
  * - add 't' to mode()
- * - set 'filetype' to "terminal"?
  * - use win_del_lines() to make scroll-up efficient.
  * - Make StatusLineTerm adjust UserN highlighting like StatusLineNC does, see
  *   use of hightlight_stlnc[].
