I'd be grateful if someone could clarify if nano can be set up for
what I call 'softwrap' for long lines. In gedit wordwrap is exactly
that and the same with emacs 'visual line mode' or Vim's set

There is softwrap in nano but it wraps long lines without removing
spaces and not saving in that mode. I wondered if it had been done in
the new release v2.3.3 but I am not able to do the compiling for a
tarball unless someone is able to guide me through.
