Thanks, Andres. Looks promising.

Here's the latest version of the patch, if you'd like to test. I don't 
expect major changes in performance, but it does add a pipe to 'sort', 
which creates some overhead proportional to the number of search results.

To enable ripgrep with this, one needs to 'M-x customize-variable 
xref-search-command-template'.
