FYI, I have not looked at how it does it, but Debian linux gets this
right.  Manpages are formatted to the screen width (be that rxvt,
cmd.exe, local VC, whatever.)  I have always found manpages more
pleasing without the vast waste of screen realestate that most 'man'
implementations have.

In fact Cygwin's "man man" mentions this:

      MANWIDTH
              If MANWIDTH is set, its value is  used  as  the  width 
manpages
              should  be displayed.  Otherwise the pages may be
displayed over
              the whole width of your screen.

...which is false on both counts: it does not honor the MANWIDTH env.var
and it does not size to the screen's natural width.
