teach fatal() to write newline

This is more robust: if a caller forgets the final newline, the
resulting messages that run together can be hard to read, whereas if a
caller adds an extra newline, it just means an extra blank line in the
output.

Rename the function when changing the interface so any callers that
have not been adjusted will break the build.  No change in
functionality intended.
