Does this need a changelog entry?

I think yes, this counts as a new feature so it should have a changelog entry.

Looks good to me, thanks @stevew817 for your work!

There's just a bunch of trivial style issues remaining as indicated in the comments.

Since there's no cleanup, it would be more readable to use return( status ) instead of goto exit (and return( whatever ); instead of status = whatever; goto exit;). I don't consider it a blocker.
