deploy_trac.wsgi contains syntax errors

[bldewolf@…]

After upgrading Trac to 0.12.2, the new deploy_trac.wsgi file has syntax errors and cannot be executed by the web server. Applying these changes allows it to work:

     return dispatch_request(environ, start_request)

However, given the changes here, it makes me suspect the script expects to be interpolated when it is not (the shebang line is "#!${executable}", which is where this suspicion came from). With this in mind, this is probably not the proper fix but a symptom of some other issue and it just happens to work in its current state.

For completeness, this was built in gentoo, package www-apps/trac-0.12.2. However, building it from the package without any gentoo special sauce yields the same broken deploy_trac.wsgi.

The deploy_trac.* scripts are indeed intended to be passed through Genshi, which is done when you execute trac-admin $ENV deploy (see TracAdmin). I have just checked that the interpolation works correctly on 0.12-stable.
