From: Ivan Andrus
Subject: bug#11759: 24.1.50; word-wrap should wrap on non-words if the current word is too long
Date: Thu, 21 Jun 2012 18:27:50 +0200

Setting word-wrap is generally a very nice addition and I like it even
when programming.  However it can cause annoying behavior when the
"words" are very long.  For example if the entire line is one "word" but
indented, which is not uncommon in some files that I regularly edit,
then the entire line is wrapped to the next line leaving a completely
blank visual line.  Arguably this is bad programming style, but it would
be nice if I could specify a maximum length for a "word".  If it would
require breaking longer than this limit, then it should break as if
word-wrap were off.

Below is a contrived example of what can cause problems when the buffer
is not sufficiently wide.
