Hi, I'm CGI-Application's maintainer in Fedora.

Yup. I decided to err on the side of caution. Like you, I tend to think
this is overkill but you never know what an application's ENV contains
and I can see CGI-Application's behaviour coming as a surprise.

Indeed. I took the liberty of taking only the parts of the patch that were
important and leaving the code reformatting pieces behind. As a result, the
patch Fedora ships is less intrusive than the one submitted upstream.

You can get a copy of the patch by running the command:
git clone git://pkgs.fedoraproject.org/perl-CGI-Application
