> If a username is a substring of a policy rule's static text then the username 
> substitution fails. For example:
> {{    if (!_qd_policy_approve_link_name("em", "temp-${user}", "temp-em"))}}
> {{        return "proposed link 'temp-em' should match allowed links with 
> ${user} but does not";}}
> Since the username *em* is found in the fixed text of *temp-* then the 
> substitution logic goes awry and the match fails. Thanks to aconway for 
> making this observation.
