What to do with /reference-implementation/ #162
Description
From my reading of https://url.spec.whatwg.org/ only "%2e" should be percent-decoded if it appears in the path section (haven't examined other sections of the url yet).
The reference implementation doesn't seem to decode any percent-encoded stuff in the path (not even %2e). But my browser (chromium) appears to percent-decode a bunch of stuff. Guessing approximately the inverse of the "default encode set".
