OK, reviewing the code, the ">" check we already have is fine - in fact
the new patch's check is one character too strict (but in a safe way).
Oldstable has 0.37-6, so this is already fixed in all supported Debian
versions.
I pinged carnil on IRC, and he said to just close if the patch we have
is enough.
Cheers,
