// 4.3.15. Consume the remnants of a bad url
//
// This section describes how to consume the remnants of a bad url from a stream of code
// points, "cleaning up" after the tokenizer realizes that it’s in the middle of a
// <bad-url-token> rather than a <url-token>. It returns nothing; its sole use is to consume
// enough of the input stream to reach a recovery point where normal tokenizing can resume.
//
// Repeatedly consume the next input code point from the stream:
//
// ** U+0029 RIGHT PARENTHESIS ())
// EOF
// ==> Return.
//
// ** the input stream starts with a valid escape
// ==> Consume an escaped code point. This allows an escaped right parenthesis ("\)") to
// be encountered without ending the <bad-url-token>. This is otherwise identical to
// the "anything else" clause.
//
// ** anything else
// Do nothing.
/**
* This is a tokenizer method which <B>"consumes"</B> the next {@code BadURL}-Token from the
