Strangely:

$ rpm -qf /usr/share/perl5/Text/Wrap.pm
perl-5.16.3-242.fc18.x86_64

Inside the actual file it says:

$VERSION = 2009.0305;

So it looks as if the version included in Perl (and hence in Fedora)
is quite old.

Anyhow, does the attached patch help?

Rich.

Subject: [PATCH] podwrapper: Set Text::Wrap::huge property to "overflow".

This stops long URLs from being broken in the text output mode.
