…ect. Imported from wvtest commit a975b39ddcca5c894e2e2b656b8e28c11af36f47. Because of changes to wvtest.py's chdir() handling, had to make some slight changes to filenames used by the bup tests themselves - all changes for the better. Signed-off-by: Avery Pennarun <email@example.com>
The forcing of version 2.5 was leftover from before, when it was accidentally selecting python 2.4 by accident on some distros when both versions are installed. But actually that's fine; bup works in python 2.4 without problems. So let's not cause potentially *more* portability problems by forcing python 2.5 when it might not exist.
