new wrapping problem in plain text messages, and odd html2text configure issue

As I continue to dig myself a deeper hole with now both send and  
receive problems (all semmingly inconsistent) with several email  
addresses actually hosted by yahoo (or is it now verizon?) I seem to be  
finding additional issues. (worst domain is frontier.com, intermediate  
problems with sbcglobal.net, and least usually with yahoo.com)

With balsa compiled from git head, I see a strange behavior, viewing  
plain text emails.  When first displayed, most of the time, the message  
appears "correctly" wrapped - that is wrapped shortly before the right  
edge of the window.  This is either in the message pane within the main  
window, or if I open the message in it's own window.  However, if I  
make the window narrower, the message does not re-wrap.  If I make it  
wider, it does re-wrap to the larger width, but does not reverse the  
process if I then make the window narrower again.  Even stranger is  
that I have found a small number of messages which start out wrapped at  
what seems to be maybe a few words or few dozen characters wider than  
the window.  I have compiled with both gtkhtml4 and webkit2, with and  
withouk gtksourceview, with no apparent difference.  Switching to  
another message and back resets to the starting situation.  This is now  
beginning to drive me crazy, as I can see no reason for this behavior.   
I have no idea when it started happenning.  I don't recall it with  
vanilla 2.5.3, but really can't be certain.

The other issue I recently noticed is that ./configure is explicitly  
looking for python-html2text, but my current version of that  
application (2016.5.29) provides pyhtml2text.  Creating a symlink lets  
configure find it, so it's not a big issue for me, but I have no idea  
whether balsa changed what it is looking for, or if the python piece  
changed the name of what it installs.  I don't have an older version  
easily available for me to check.  (I do have two newer versions  
available, but both still marked as testing.)

As alwasy, thanks for any suggestions.
