[wmii] [PATCH] add wimenu prompt support

From: Bart Trojanowski <bart_AT_jukie.net>
Date: Sun, 29 Mar 2009 21:32:49 -0400

This patch adds wimenu -p option that prepends an optional prompt box at
the left of the input area. Here is an example:

        seq 1 100 | wimenu -p 'What number am I thinking of?'
