If you use ada-mode with emacs, then this is a non-issue.  The open
paren goes where you expect it (see below), and it can format the entire
parameter list (C-c C-f), even getting rid of that nasty space that
preceeds the semicolons.  

procedure Pop
  (Item :    out Element_Type;
   List : in out List_Type);


I live by these words:

"Get a life.  Get emacs."  

Life is good...
