I agree. I haven't had much time to think about this, but I think
it might be quite a challenging project. I need to get up to speed
on Keith's project...

Because the double quotes are part of the operator name... Eg:

    function "+" (A, B: My_Type) return My_Type;

And if we wanted to be pedantic, the debugger should also accept:

    (gdb) break '"+"'

By comparison, '+' is an entirely different thing (the character +),
and thus breaking on '+' should be rejected.

That being said, if it helps Keith's work to treat them similarly,
then I don't mind being a little approximate here, and treat both
quote characters as the equivalent for linespec purposes. I doubt
that any Ada programer would ever write...

    (gdb) break '+'

... and if that were the case, that he'd complain much about it
inserting a breakpoint on operator "+".
