Link creation bugs in GitHubWeb-flavored extension

[isoos]

Original report on pub-dev: dart-lang/pub-dev#6126
Markdown version: 6.0.1

1. Extra text content after the link closing tag:

dart run markdown --extension-set GitHubWeb
(https://github.com/intel/rohd/issues/129)
<p><a href="https://github.com/intel/rohd/issues/129">https://github.com/intel/rohd/issues/129</a>9)</p>

2. href URL with extra parenthesis, also in the link text content:

dart run markdown --extension-set GitHubWeb
(https://github.com/intel/rohd/issues/129).
<p><a href="https://github.com/intel/rohd/issues/129)">https://github.com/intel/rohd/issues/129)</a>).</p>

@chenzhiguang @srawlins: any ETA when this (and other fixes) will get released?

I'm hoping within a month.
