suppress auto-linking

[jmdyck]

Sometimes we don't want ecmarkup to auto-link a word. For example, see tc39/ecma262#1730 and tc39/ecma262#1731.

It would be nice if ecmarkup would:

• suppress auto-linking within the <div id=metadata-block> element; and/or
• allow the document to spot-disable auto-linking via some markup (e.g.: <span class="do-not-autolink">Mailing List Archives</span>)

See:

• "Property name" incorrectly linked when used for Unicode property escapes ecma262#1079
• List in "Mailing List Archives" auto-linked ecma262#1730
• 'InitializeBinding' incorrectly links to 'Record' spec type ecma262#1875
