A value of nil means don't display a mode line.

-For a list of the form `(:eval FORM)', FORM is evaluated and the result
- is used as a mode line element. Be careful--FORM should not load any files,
- because that can cause an infinite recursion.
-For a list of the form `(:propertize ELT PROPS...)', ELT is displayed
- with the specified properties PROPS applied.
-For a list whose car is a symbol, the symbol's value is taken,

-For a list whose car is an integer, the cdr of the list is processed
- and padded (if the number is positive) or truncated (if negative)
- to the width specified by that number.

+ `risky-local-variable' property, all properties in any strings, as
+ well as all :eval and :propertize forms in the value, are ignored.
+
+A list whose car is a string or list is processed by processing each
+ of the list elements recursively, as separate mode line constructs,
+ and concatenating the results.
+
+A list of the form `(:eval FORM)' is processed by evaluating FORM and
+ using the result as a mode line construct. Be careful--FORM should
+ not load any files, because that can cause an infinite recursion.
+
+A list of the form `(:propertize ELT PROPS...)' is processed by
+ processing ELT as the mode line construct, and adding the text

+
+A list whose car is a symbol is processed by examining the symbol's
