   "Call `redisplay' to trigger mode-line height calculations.

 Certain functions, including e.g. `fit-window-to-buffer', base
 their size calculations on values which are incorrect if the
 mode-line has a height different from that of the `default' face
 and certain other calculations have not yet taken place for the
 window in question.
+
 These calculations can be triggered by calling `redisplay'
 explicitly at the appropriate time and this functions purpose
 is to make it easier to do so.

 This function is like `redisplay' with non-nil FORCE argument.
 It accepts an arbitrary number of arguments making it suitable
