    This is in the "tough problem" category.  Since finding the
correct declaration requires parsing the file and doing overload
resolution, it is only possible to do this for source files which are
correct compilable Ada.  (And, of course, with reference to a
particular program library.)

    The rule I have used for formatters which accept non-legal
programs is either to use the first appearance of an identifier in the
file OR to use a particular rule and have a file of personal
exceptions.  What I keep intending to do is build a tool that takes a
file of starname style exceptions:

    *_IO
    ADAR_*
    SPARC_*
    ...

    hmmm...an easier case might be to treat underscores as separators:

    IO
    ADAR
    SPARC

    that would make a fairly simple standalone tool.

    My plate is fairly full right now, but if anyone wants to work on
this, I'll be glad to help supply the easy 75%. (The pieces already
done of course. :-)
