[mod_python] CWD in PythonPath

There doesn't appear to be a way to put the current working directory 
in the path using the PythonPath directive.  It does fine when a module 
in the directory in question is named in a handler directive when 
PythonPath is not set.  But when I do set PythonPath, it can only pick 
up modules in directories explicitly named in the path.

I currently have
PythonPath "sys.path + ['/home/www/import']"
as the directive, but I have also tried expanding sys.path out in the 
directive with both '' and '.'.  Still not luck.
