Given our time constraints I intend to apply this to HEAD and backpatch
it to 8.2 and 8.1, unless there's a strenuous objection. That will give
us some buildfarm coverage on it, although we don't seem to have any
perl 5.6.x on the buildfarm that I could see. We've had a positive test
report, no negative reports, and I'm fairly sure the patch is at worst
harmless.
