   This is the part of the Emacs manual (under "7.10 Numeric Arguments")
   that describes how a prefix argument changes the meaning of a command
   like C-r:
   Some commands care whether there is an argument, but ignore its
   value. For example, the command ‘M-q’ (‘fill-paragraph’) fills text;
   with an argument, it justifies the text as well. (*Note Filling::, for
   more information on ‘M-q’.) For these commands, it is enough to specify
   the argument with a single ‘C-u’.
