[Python-Dev] PEP 229 checked in

Look at the logic in Modules/getpath.c, which calculates the initial
(default) sys.path.  It detects that it's running from the build tree
and then modifies the default path a bit to include Lib and Modules
relative to where the python executable was found.

It's not jut for 'make test' -- it's to make life easy for developers
in general (and me in particular :-) who want to try out their hacks
without going through 'make install'.
