When you set `Man-width' to a positive integer, the manpage's text is
formatted to that width.  This variable doesn't affect the window's width.

But what if you have manpage buffers in both of horizontally split
side-by-side windows?

Do you think `Man-width' should be mentioned in the docstring of `man'?

Maybe the docstring of `Man-frame-parameters' should provide an example
of using the frame parameter `width'?

`Man-frame-parameters' is ignored unless `Man-notify-method' is set
to the value `newframe'.  However, I don't know how the users
who prefer to set `pop-up-frames' to a non-nil value
specify the width of the manpage's frame
(when `Man-notify-method' is not `newframe')?
