ripgrep: add --no-pre switch

Browse Source 
This switch explicitly disables the --pre behavior. An empty string will
also disable --pre behavior, but actually utterring an empty flag value
is quite awkward, so we provide an explicit switch to do the same thing.

Thanks to @c-blake for pointing this out.
