Hi,

Thanks for this, it seems to implement the approach that I'd planned but
haven't had time to do myself. I'll try to get it in for the 4.8 release.

To make sure it doesn't get lost, could you please attach this patch to
the bug at:

https://bugzilla.mindrot.org/show_bug.cgi?id=993

Before you submit it, it would be best if you could review it in light of
the style guide[1] - I noticed that it uses spaces instead of tabs and
doesn't do indenting quite the same way as the existing code.

Thanks,
Damien
