Bug#823446: cowpoke fails on symlinkedd .orig.tar.gz

[Antoine Beaupré]

Package: devscripts
Version: 2.15.3
Severity: normal

It seems to me like fairly common practice to have symlinked
.orig.tar.gz files. Yet cowpoke seems incapable of managing those
files. I see this:

$ cowpoke --buildd=marcos.anarc.at --dist=wheezy --arch=amd64 ../xen_4.1.6.1-1+deb7u1.dsc
cowssh_it

Can we support those files please?
