 12.2 Macros with semicolons
 ===========================
 
 Macros which needn’t (or mustn’t) be followed by a semicolon when you
 invoke them, “macros with semicolons”, are very common.  These can cause
 CC Mode to parse the next line wrongly as a ‘statement-cont’ (
 Function Symbols) and thus mis-indent it.
 
    You can prevent this by specifying which macros have semicolons.  It
 doesn’t matter whether or not such a macro has a parameter list:
 
  -- User Option: c-macro-names-with-semicolon
      This buffer-local variable specifies which macros have semicolons.
      After setting its value, you need to call
      ‘c-make-macro-with-semi-re’ for it to take effect.  It should be
      set to one of these values:
 
      nil
           There are no macros with semicolons.
      a list of strings
           Each string is the name of a macro with a semicolon.  Only
           valid ‘#define’ names are allowed here.  For example, to set
           the default value, you could write the following into your
           ‘.emacs’:
 
                (setq c-macro-names-with-semicolon
                      '("Q_OBJECT" "Q_PROPERTY" "Q_DECLARE" "Q_ENUMS"))
 
      a regular expression
           This matches each symbol which is a macro with a semicolon.
           It must not match any string which isn’t a valid ‘#define’
           name.  For example:
 
                (setq c-macro-names-with-semicolon
                      "\\<\\(CLEAN_UP_AND_RETURN\\|Q_[[:upper:]]+\\)\\>")
 
  -- Function: c-make-macro-with-semi-re
      Call this (non-interactive) function, which sets internal
      variables, each time you change the value of
      ‘c-macro-names-with-semicolon’.  It takes no arguments, and its
      return value has no meaning.  This function is called by CC Mode’s
      initialization code.
