Auto-generated hyperlinks are broken if they contain more than one issue number

URLs in fields are automatically converted to hyperlinks by JIRA. If the URL also contains 2 (or more) valid issue keys, it gets garbled.

Examples of such broken URLs are:

http://foo.example.com/?foo=TST-16650&bar=TST-16650
http://foo.example.com/TST-16650/TST-16650/index.html

Note that this bug only affects the Default Text Renderer; the Wiki Style Renderer is unaffected.

Since jira.atlassian.com is using the Wiki Style Renderer, you can see the problem by viewing the change history of the bug instead.
