I see a lot of posts written via GoldED and formatted  to  a
limited  line  width, usually the standard 72 charactes.  It
must be configurable in the settings.

This is hightly non-standard, for readers are  not  required
to warp long lines.  In Usenet, Fidonet, and e-mail, this is
the responsiblity of  the  sender.   Here  is  the  relevant
excerpt from GNKSA, but you shall find statements to similar
effect in RFC and other standards and guidelines:

   14)  Try  to   respect   the   80-character   line-length
   conventions

   Any  line  breaks  shown to the user while she is editing
   her article SHOULD still be present when the  article  is
   actually posted to the Net.  The software SHOULD NOT show
   the user four 75-character lines while actually posting a
   single 300-character line.  Nor should it show the user a
   series of  100-character  lines  while  actually  posting
   alternating lines of 80 and 20 characters each.

   It's also a good idea to warn the user if the article she
   is about to post contains non-header lines longer than 80
   characters.  The software SHOULD NOT prevent the posting,
   but SHOULD ask whether the user wants to re-edit or  post
   anyway.

A  standard-conforing  way  to have a flexible line width is
