[pacman-dev] Bad error message on invalid pacman -S operation

I did "pacman -S" today instead of "pacman -U", and I noticed the error message is not all that great, and I think this is a regression: dmcgee@galway ~/projects/arch-repos/valgrind/trunk $ pacS /home/makepkg/packages/valgrind-3.4.1-1-x86_64.pkg.tar.gz Password: error: repository '' not found error: '/home/makepkg/packages/valgrind-3.4.1-1-x86_64.pkg.tar.gz': no such repository
