[PATCH] panelize indicator

[Tomas Styblo <tripie cpan org>]

Hello.

This patch adds an indication of the "panelized" mode to the title
of the panel. Currently there exists no indication when the panel
is in the panelized mode, which is very confusing.

The patch also fixes a buffer overflow on screens with more than
200 columns, which is not impossible with high resolutions and/or
small fonts.

The only modified file is screen.c.

Regards.
