Vim: highlight long lines only for some file types
Vim: highlight long lines only for some file types

For a while now I've found the long line highlighting to be annoying for
some file/buffer types, particularly things like the MiniBufExplorer
window, which can have an extremely long line once you've been working
for a while and have opened dozens of files.

So instead of highlighting everything, I'm going to start selectively
highlighting some filetypes only (rather than excluding unwanted types,
will include wanted types), starting with Ruby.
