url's with javascript scheme should not be links in reST A javascript url in a reStructuredText document should not be displayed as a link. So: javascript:nastyJavascriptCode should be displayed as text and not a link. We do this by stripping the scheme from the schemes array in docutils.utils.urischemes. We set a property on the StringHTMLProperty to hold the list of schemes we want to disable so the user can choose to change it if they want.
