Tidiness is the only reason.

Please don't hesitate to nack this patch if you think we shouldn't
change the historical behaviour, the cleanup is very minor.

As for me, I think it is a bit strange we append "%.pid" depending on
is_multithreaded, the same app can have 1 or more threads for various
reasons when the coredump happens, but this behaviour is very old and
perhaps it is too late to change.

Oleg.
