From: Bram Moolenaar <Bram <at> moolenaar.net>
Subject: Patch 7.4.338
Newsgroups: gmane.editors.vim.devel
Date: Wednesday 25th June 2014 12:40:05 UTC (over 2 years ago)
Patch 7.4.338
Problem:    Cannot wrap lines taking indent into account.
Solution:   Add the 'breakindent' option. (many authors, final improvements
by
	    Christian Brabandt)

+ 			    text should normally be narrower. This prevents
+ 			    text indented almost to the right window border
+ 			    occupying lot of vertical space when broken.
+ 		shift:{n}   After applying 'breakindent', wrapped line
+ 			    beginning will be shift by given number of
+ 			    characters. It permits dynamic French paragraph
+ 			    indentation (negative) or emphasizing the line
+ 			    continuation (positive).
+ 		sbr	    Display the 'showbreak' value before applying the
