I need not admit it. :-)  (For that matter, it is trivial to do this
in Emacs, and not at all hard in vi.)

The gain appears because you may not have access to the source
definition.  People with El Stinko C Version 17.34 for the MiniMega
Model M probably do not *have* the source to fopen() or putc(), but
they *do* have a readable <stdio.h> containing the types (and, if they
are lucky, some suggestive names) for the arguments thereto.
