The rule to detect "()" without a "void" is fine, but why on Earth do
we need the other rule, about prototypes like this:

  int
  foo (bar);

This is a perfectly valid formatting.  In your patch, you modify long
prototypes like this as follows:

   extern struct hppa_objfile_private *
  -hppa_init_objfile_priv_data (struct objfile *objfile);
  +  hppa_init_objfile_priv_data (struct objfile *objfile);

But that is not a good idea, because if you type TAB in Emacs on the
line with the function name, Emacs will reindent the name to column
zero.  So I expect this rule to annoy us quite a bit, e.g. if someone
reindents a large region.

Can you tell why we need this?
