Split the patch?
If not, the bigger part by far is the return value change, so I'd put
that into the subject.

Not this patch's problem, but here goes anyway: since this isn't an
error, we shouldn't use error_report_err(). Would warn_report_err() be
appropriate? info_report_err() doesn't exist, but it could.
