1.4.17
introduce path.exists() path.isdir() path.isfile() shortcuts
remove trailing whitespace everywhere
move test files out of py lib proper * separate all tests from plugins * simplify implicit inclusion of plugins under test * have test_initpkg perform direct checks instead of yielding tests * fix example tests for 3k
don't depend on (and don't actually use anymore) testing/__init__.py
avoid empty lines when separator-lines are printed by being defensive and reducing the working terminalwidth by 1 also xfail expanduser test on python2.5/win32
fix internal test, thanks thm
try to fix failures related to subversion 1.7.
