There are 2 potential problems in archlinux.vim.

1. nocompatible is set unconditionally. If someone sets nocompatible in /etc/vimrc and does a bunch of configuration below that and then sources archlinux.vim at the bottom, nocompatible is set a second time, which may break/undo some of the configuration done before.

2. suffixes is overwritten rather than added to (suffixes=foo instead of suffixes+=foo). If the vim maintainers decide to add a bunch of new suffixes to the list Arch users won't see them.

I've fixed both of them in good.patch and also cleaned the file up a bit. (I've also removed 'set history=50' because 50 the default value.) The resulting configuration should be identical.

I've also included better.patch which removes a lot of stuff from archlinux.vim that I don't think makes much sense to have in there. The suffix option is way too personal for archlinux.vim (or /etc/vimrc even), XTerm mappings probably are best kept in the ~/.vimrc of a XTerm user and the CVE-workaround should probably be in ~/.vimrc too because no other distro includes it globally so if you log in to a server from your Arch desktop you won't be protected. I've also added 2 options from defaults.vim and sensible.vim, making archlinux.vim basically a tiny subset of both of them.

Feel free to pick the patch you like best. Thanks.
