I think that wikipedia.Page.getVersionHistory has a bug.
The function getVersionHistory return without edit summary at least in
Japanese Wikipedia.
The local variable editR is wrong.
The following version may work:
editR = re.compile(r'<li>\([^\)]*\)
\([^\)]*\) <[^>]*><[^>]*> <a
href="[^\'"]*oldid=(\d*)"[^>]*>([^<]*)</a> <span
class=[\'"]history-user[\'"]><a
[^>]*>([^<]*)</a>(?:[^<]|<(?!span
class="comment">)(?!/li>))*(?:<span
class="comment">\((.*)\)</span>)?.*</li>', re.UNICODE)
I've tested this code rough.
Sorry for my poor English. Thank you.
