+This variable has three potential sets of values:
+
+- t: automatically calculate the number of columns possible based
+ on the tags to be shown and the window width,
+- an integer: a lower bound on the number of characters that will
+ be used to display each column,
+- a float: a fraction of the window width that is the lower bound
+ on the number of characters that should be used for each
+ column.
+
+So:
+- if you would like two columns of tags, set this to 0.5.
+- if you would like a single column of tags, set this to 1.0.
+- if you would like tags to be 30 characters wide, set this to
+ 30.
