big_file_options.vim

This plugin adds an autocmd hook to check the file size of an incoming buffer, and if it's over a certain threshold, disables certain options in order to make the file a bit easier to edit. It makes the buffer read-only, and disables filetypes, swap files, undo files, and syntax highlighting.
