 <code>  --xavgcharwidth [N]     </code><i>Adjust xAvgCharWidth (optional: concrete value)</i>
 </summary>
 In some very rare cases the <code>xAvgCharWidth</code> is important to keep. Patching in wider icons changes this value.

-Just specifying the option without number will use the 'old' western-centric algorithm to calculate the
-average x width (which ignores our added icons). But you can also specify a concrete number.

+<ul>
+<li>If just the option is specified (without numbger) the <code>xAvgCharWidth</code> is copied over from the source</li>
+<li>If a number is added that number is used as <code>xAvgCharWidth</code></li>
+<li>If the number added is zero we will calculate the old style <code>xAvgCharWidth</code>, which ignores our added icons</li>
+</ul>
