I hope the comment is sufficient explanation.  I set COLUMNS in the
cause of generality rather than MANWIDTH, which might be safer, but I
doubt it will break anything.  (I don't know why man is actually
getting it wrong and not defaulting to 80 columns; it DTRT in a shell
buffer.)

        * man.el (Man-getpage-in-background): Maybe set COLUMNS in
        environment.
