Since commit 50b7b000, we have error_append_hint() to conveniently accumulate Error member @hint. error_report_err() prints it with a newline appended. Consequently, users of error_append_hint() need to know whether theirs is the final line of the hint to decide whether it needs a newline. Not a nice interface. Change error_report_err() to print just the hint, and the (still few) users of error_append_hint() to add the required newline.
