Patch 7.4.353
Problem:    'breakindent' doesn't work with the 'list' option.
Solution:   Make it work. (Christian Brabandt)

+ 		min:{n}	    Minimum text width that will be kept after
+ 			    applying 'breakindent', even if the resulting
+ 			    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', the wrapped line's
+ 			    beginning will be shifted by the 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 
+ 			    additional indent.
+ 	The default value for min is 20 and shift is 0.
