It probably means what it says. You can format man pages with a
variable number of characters per line, hence you might have "(setq
Man-width 75)" in your ~/.emacs to get a reasonably formatted display
rather than one with the lines being too long for comfortable reading.
Now say, you specify zero characters per line, and the software may
suddenly have a hard time adjusting the lines.
In case lee's unclear: the output of "man" isn't going to your terminal
any
more, so it doesn't know how wide the output should be.
Personally I would expect it to default to assuming an 80-column output and
format for that. But it appears not.
