Hello!

When using "\\" to force linebreaks, these potentially get lost when
reformatting the paragraph with Alt+Q (fill paragraph).

Given an input

  :  - long sentence long sentence
  :    long sentence long sentence
  :    long sentence long sentence
  :    long sentence: \\
  :    Next line.

pressing Alt+Q (`fill-paragraph') I'd expect to get

  :  - long sentence long sentence long sentence long sentence long
  :    sentence long sentence long sentence: \\
  :    Next line.

but what I get is

  :  - long sentence long sentence long sentence long sentence long
  :    sentence long sentence long sentence: \\ Next line.

This is a problem especially as a "\\" anywhere but at the end of the
line is exported literally (i.e. `fill-paragraph' changes both the
appearance in emacs and in exported formats).

The Problem occurs in the opposite direction too: If a "\\" is  m e a
n t  to occur literally it can end up at the end of a line and thus be
interpreted as a line break.

The problem can be partially avoided by marking each "line" and /then/
pressing Alt+Q, but it is inconvinient and hinders fille-wide
reformatting (e.g. when the variable `fill-column' has changed).

Yes, this is a problem. I'll take a look at it in a few days. I wanted
to provide a better filling mechanism backed up with Org elements,
anyway.

I've committed a patch that should prevent auto-fill from creating Org
line breaks.
