Jonathan's proposed output looks fine to me.  The "candidates are" note had a
source location for the sake of dejagnu, but we can deal with that by adjusting
the prune.exp note handling.

But I also want a general solution to the issue of multiple diagnostics with
the same source location; overload resolution isn't the only example.

I think suppressing the caret by default for notes makes sense.
