Subject: textfill: default fill:end-re to fill:start-re
X-Git-Url: http://git.neil.brown.name/?a=commitdiff_plain;h=897009a2d260e34a1198cfdfbafd9ce0ff457e39;p=edlib.git

textfill: default fill:end-re to fill:start-re

The regexp for start and end of para are usually the same, so if end-re
isn't given, use the same as start-re.

Use this to simplify md config, and enhance it a bit.
