or more additional messages to stderr:

Anybody knows what this means? No such message if the gnome terminal is
wide enough.
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.
Hi Cameron,
Sounds reasonable.
Personally I would expect it to default to assuming an 80-column output and
format for that. But it appears not.
I filed a BZ.
being that no one asked, i will.
why would someone send a man page to a null device?
to a printer, file, another terminal, yes. /dev/null, never.
because intent of 'man' is not to send output to /dev/null,
why should it written to do so?
such is not intent of 'man', therefore, i would not consider
doing such as a bug. other than person doing so. ;-)
