Ambiguity in documentation of `Url::query_pairs()`

[apt1002]

The documentation for Url::query_pairs() does not make it clear whether the returned values are %-decoded. The docs for Url::query() explicitly say that the returned string is not %-decoded, which might lead the reader to guess the same for Url::query_pairs(), but my testing suggests that in fact query_pairs() does %-decode the returned values.

Observed:

Parse the URL’s query string, if any, as application/x-www-form-urlencoded and return an iterator of (key, value) pairs.

Expected:

Parse and decode the URL’s `application/x-www-form-urlencoded`-encoded query string, if any, and return an iterator of the (key, value) pairs.
