There's no such thing as "the rspec load path", and I think it might confuse users to suggest there is one.  I think it's sufficient to say:

> Use the `--require` (or `-r`) option to specify a file to require before running specs.

Anyone who knows what the ruby load path is will understand that's how `require` works, and there's no need to mention it.

(Also, notice my use of backticks: this helps it render better on relish).
