I cannot reproduce this on my system, but I think I know why, see
below.

That's because Emacs 20 didn't set COLUMNS in the environment before
invoking the `man' program. But that had other adverse effects on X,
see the comments in man.el where it sets COLUMNS.

Actually, it does have something to do with Cygwin: I'm guessing your
man.exe comes from Cygwin, and tries to honor the COLUMNS environment
variable. My man.exe is a natively compiled clone of the Unix `man'
command, and it doesn't pay attention to COLUMNS, so it always
produces text whose width assumes an 80-column display, no matter what
COLUMNS says.
