This patch implements proper ERT behaviour for normal layouts.

In particular, it makes paragraph breaks generate single \n in latex output
when ParbreakIsNewline is true

This means that it is not necessary anymore to use newlines to break lines. 
Plain paragraph breaks can be used instead, like is done now in ERT/Listings. 
This is mainly aimed at sweave support.

#Category: literate
# Suggested style to write your code:
# Within same scrap, lines are separated by newlines (Ctrl-Return), use:
# ItemSep 0.4
# . disavantage: must type ctrl-return every single line
# . advantage: looks better (IMHO)
# resembles more closely the produced paper doc (more WYSIWYG)
