Preview mode: Urls containing hashtags are broken and not styled properly

[laraconda]

Describe the bug

When you add an url with '/#', the preview shows the string that follows the # as a tag. Moreover, the href in <a> tags contains <span> tags that should not be there.

Example of one of the links after being processed by t2t: <a href="http://www.mywebsite.org/<span style="color:red">#foo</span>/bar">http://www.mywebsite.org/<span style="color:red">#foo</span>/bar</a>

Visual:

When I disable the hashtag recognition in util/markup.py, the bug goes away, except that the full url is still not recognized as such correctly:

Trying to fix this problem by adding a '/' in the right regex in external/txt2tags.py makes the whole (from beginning to end) url to be marked as such, as it should be, but the hashtag is still recognized as a hashtag and the problem regarding spans in hrefs is still there.
