Links generated by the wiki are invalid when they contain something that could be an email. For example, this :


http://foo@www.bar.com


is transformed to


www.foo@bar.com\">http://www.foo@bar.com


and rendered as this http://foo@www.bar.com in a web browser.

I observed this problem by using @hg fetch@ that generates commit messages like :


Automated merge with https://login@hg.foo.com/project.


Here is a patch that solves the problem and a unit test. The code come from http://dev.rubyonrails.org/changeset/7516. The only limitation of this solution is in that case :


http://foo@bar.com foo@bar.com


where only the first link is detected. I did not found the magic regexp. Maybe this could be solved with some lookbehind but the syntax is not supported on ruby 1.8.
