Bug#367818: /usr/share/vim/virc symlink is missing

[sacrificial-spam-address at horizon.com]

Package: vim
Version: 1:6.4-007+1

When invoked as vi, /etc/vim/virc is never invoked.  This is because
vim is sourcing $VIM/virc, and $VIM is /usr/share/vim, which has symlinks
to /etc/vim for vimrc and gvimrc... but not virc.

FWIW, I still like to have a vimrc.local for common changes that I don't
want to copy to both vimrc and gvimrc.  You can rename it to vimrc.common
if you like, but it's still convenient.

Anyway, thanks!
