If a URL contains a change ID such as
http://example.org/change/123abc456/log.html then the changeid regex
matches the id and tries to turn it into a link like:
http://example.org/change/<a href="#q,123abc456,n,z">123abc456</a>/log.html
which clearly breaks the original URL.
To fix we should check for whitespace or periods around the changeid
in the comment. Also, check for <p> tags that gerrit adds to comments
for us.
