[Python-modules-team] Bug#816218: email link encoded twice

[Enrico Zini]

Package: python-markdown
Version: 2.6.5-2
Severity: normal

Hello,

thank you for maintaining markdown.

I have noticed that rendering email links generates a rather overquoted
href:

$ python3
Python 3.5.1+ (default, Jan 13 2016, 15:09:18) 
[GCC 5.3.1 20160101] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import markdown
>>> markdown.markdown("<test at example.org>")
'<p><a href="mailto:test@example.org">test@example.org</a></p>'
>>> 

Chromium opens it correctly, so I wonder if this is just some antispam
measure. However, chromium opens it correctly, so I'm not sure it is
really useful as an antispam measure.

Looking at AutomailPattern's implementation in inlinepatterns.py it
seems intentional, and I think it should at least be documented, and, if
possible, configurable.

This is making it rather complicated for me to postprocess <a> links in
the markdown ElementTree.


Thank you,

Enrico
