Subject: Man-width on terminals
Date: Thu, 08 Nov 2007 02:54:52 +0200 [thread overview]
Message-ID: <87ejf17e85.fsf@jurta.org> (raw)
Terminals don't necessarily have 80 columns nowadays but man.el still
limits the width of the formatted man pages to 80 columns on non-window
systems, and it's impossible to override this with an user option.
I propose to remove this restriction that treats terminals as a special case,
and to allow terminals using all available horizontal space (defined by
`window-width'). This also allows using an existing user option `Man-width'
to define any other desired width equally on terminals and window systems:
