remove 'luochen1990/rainbow' plugin to fix "magic" syntax highlight.
Fix #875
I believe the formatting you are seeing is expected behavior for rainbow, as demonstrated in this screenshot from the project's page.

Perhaps disabling the plugin is all you need?

Thanks to notice this.
I believe it's a 'magic highlight' after anyone first to use or upgrade the spf13.
So, if someone like it, he can add this plugin to .vimrc.bundles.local by himself.
But if it's a 'welcome change', we can keep it on and ignore my PR.
Yeah that's a fair point. Maybe @jrobeson would want to weight in? I personally don't use rainbow.
In the mean time, you can set let g:rainbow_active = 0 in your vimrc to disable it by default, or of course unbundle it.
I don't use rainbow either.
Also fixes #850. Thanks, this has been annoying the heck out of me for months.
Thank you.
let g:rainbow_active = 0 Fixed my issue. Thank you @bronzehedwick
Who likes rainbows anyway.
