Add modeline to highlight.vim
Add modeline to highlight.vim

I've always viewed highlight.vim with syntax off because the long lines
cause syntax highlighting to slow down my Vim, so I just put it in a
modeline to do it automatically.

The other stuff are niceties: nowrap so each highlight statement is
neatly in its own line (they're long enough to get wrapped on lots of
terminal sizes), and textwidth=0 so my Error column doesn't show (commit
6a7c31447914f22e293f8713244d1924770cced4).
