This is usually not necessary, "request/start" should usually work okay.

I see! The example should probably be:

	start python: path('request/start | nothing') or 0

I think I read a post in "zpt@zope.org" (i.e. the ZPT mailing list),
that there have been recent changes (made it more consistent)
in the exception handling of "path(...)".
