Annoying padding between tmux bar and bottom of terminal window when maximised
<p>I am using tmux inside of a gnome-terminal.</p>

<p>When I first open a window (with the default size being 80x24) the tmux bar sits snugly at the bottom of the window. When I maximise the terminal window, however, an annoyingly large gap appears underneath the tmux bar. </p>

<p>This is my .tmux.conf:</p>

<pre><code>set-option -g default-command bash

# remap prefix to Control + a
unbind-key C-b
set-option -g prefix C-a
bind-key C-a send-prefix
bind-key C-a-h split-window -h #Split panes vertically

# time/no(0) time between C-a and command
set -s escape-time 0

#set-option -u repeat-time #global setting, "delete" repeat-time

set-option -g -q mouse on #activate mouse
</code></pre>

<p>How do I get the tmux bar to sit as it does in the small this when I maximise the terminal window? </p>
