The function has more parameters, so this does not set noerr to 0.

Not too happy about this, because usually passing undef and 0 for a
"boolean" is the same, but not here. And Perl won't help you. There's
not many callers, maybe just adapt them instead? Should be its own patch
then.

Style nit: we usually have something like
die $err if !$noerr;
warn $err;
which avoids the line bloat.
