infinite follow bug in issues

When I created an issue named 'follow', I met infinite redirection to

https://bitbucket.org/<account>/<repo>/issue/<num>/follow

I guess /follow is special key to make user follow the issue, but it is also used as meaningful url.

Please stop title finger special commands and save me from infinite redirection trap

ps. I also guess that you may prohibit special commands already, but in this case, i used some hangul characters on title and all of them are excluded, except 'follow'.
