Wikipedia doesn't work with Finnish Wikipedia.

Might also affect other languages.

I think this is the same error as #186, which has already been fixed. Try updating your copy of the Wikipedia plugin.

[Mikaela]

mkaysi@hilla ~/Tessu/plugins
% pwd && ll Wikipedia 
/home/users/mkaysi/Tessu/plugins
lrwxrwxrwx 1 mkaysi users 60 kesä  30 16:04 Wikipedia -> /home/users/mkaysi/src/git/ProgVal/Supybot-plugins/Wikipedia/

mkaysi@hilla ~/src/git/ProgVal/Supybot-plugins/Wikipedia
% git pull
Already up-to-date.

and the bot has been last restarted 2 ½ days ago and there haven't been changes in the Wikipedia plugin after that , so that cannot be it.

[jlu5]

Try this patch; there seems to be some minor inconsistencies in the formatting Wikipedia uses, which causes the regex matching being used in the plugin to break.

[Mikaela]

Ignore removed comment, I used wikipedia instead of wiki.

The patch works.
