I've backported this and sent it upstream for maint-5.14:

https://rt.perl.org/rt3//Public/Bug/Display.html?id=114454

I'm not sure whether it's appropriate to put this into perl for wheezy.
I think the risk of regressions is quite slim and it clearly breaks things
(there is another example of it breaking part of amanda at [1])
but it doesn't meet the letter of the release team freeze exceptions
rules.

Anyone else care to comment about how we should tackle this?

Cheers,
Dominic.
