[Murray Cumming <murrayc src gnome org>]

commit 4b069d006381da2dfd2dca04842eb8af131ecd6d
Author: Murray Cumming <murrayc murrayc com>
Date:   Tue Dec 8 09:36:33 2009 +0100

    Tests: Added glom_evaluate_python_function_implementation() tests.
    
    * Makefile_tests.am:
    * tests/test_python_execute_func.cc:
    * tests/test_python_execute_func_date.cc: Added two unit tests for
    Glom::glom_evaluate_python_function_implementation(). The date one
    currently fails, as in bug #603686.
