Re: fix -fmax-errors & notes

But what if the user has selected -Wfatal-errors and there's a single

behavior? (I'm trying to think of a case here, but failing).
good question.
I think both -Wfatal-errors and -fmax-errors=1 would now result in not emitting
the 'compilation terminated' message (and similarly for any -fmax-errors=N with
exactly N errors. Perhaps this is worth worrying about for -Wfatal-errors, but
not for -fmax-errors. If one wanted notes but only one error one could use
-fmax-errors=1. (not sure of the use case of -Wfatal-errors given
-fmax-errors=1 seems to be nearly the same?)
Perhaps the -Wfatal-errors logic should remain unchanged?
