parameters list.
New style prototyped ANSI formal parameter lists should in theory always
contain some stuff between the opening and closing parens, even if it is
only "void".
The brutal truth though is that there is lots of old K&R code out there
which contains declarations of "pointer-to-function" parameters and
these almost never have fully specified formal parameter lists associated
with them. That is, the pointer-to-function parameters are declared
with just empty parameter lists.
In cases such as these, protoize should really insert *something* into
the vacant parameter lists, but what? It has no basis on which to insert
anything in particular.
Here, we make life easy for protoize by trying to distinguish between
K&R empty parameter lists and new-style prototyped parameter lists
that actually contain "void". In the latter case we (obviously) want
to output the "void" verbatim, and that what we do. In the former case,
we do our best to give protoize something nice to insert.
This "something nice" should be something that is still valid (when
re-compiled) but something that can clearly indicate to the user that
more typing information (for the parameter list) should be added (by
hand) at some convenient moment.
The string chosen here is a comment with question marks in it. */
