[mod_python] test doesn't work (solved?)

Gee, I dunno. I kinda like the idea that the config file can completely
set the path.  It seems cleaner that way, just as scripts often do
	PATH=/bin:/usr/bin ; export PATH
rather than
	PATH=$PATH:/bin:/usr/bin ; export PATH

I vote to keep the current semantics.
