* docs: don't blow away existing query string
See comments in diff - I ran across this and it took me a while to work out why my client side code worked, but the server didn't. It was because I didn't realise that `.render`'s 3rd arg was the query object, so it was losing the _actual_ query string.
* chore: remove trailing spaces
¯\_(ツ)_/¯ I think!
