From 39ab9676914bd0d8105d0f96bbd7611a53077438 Mon Sep 17 00:00:00 2001

Subject: [PATCH] Add -g option to display entries in the given number of grid
columns
This option can be used in conjunction with -l to format dmenu's options in
arbitrary size grids. For example, to create a 4 column by 6 line grid, you
could use: dmenu -g 4 -l 6
