tests: use $PYTHON instead of hardcoding python
This makes running the testsuite with pypy possible.

$ cd ..
$ hg update b1
abort: no repository found in '$TESTTMP' (.hg not found)!

Cases are run as shown in that table, row by row.

Test that 5 is detected as a valid destination from 3 and also accepts moving
the bookmark (issue4015)
$ hg up --quiet --hidden 3

1 files updated, 0 files merged, 0 files removed, 0 files unresolved
$ hg book bm
moving bookmark 'bm' forward from 6efa171f091b

Test that 4 is detected as the no-argument destination from 3 and also moves
the bookmark with it
$ hg up --quiet 0 # we should be able to update to 3 directly
$ hg up --quiet --hidden 3 # but not implemented yet.

Test that we don't crash when updating from a pruned changeset (i.e. has no
successors). Behavior should probably be that we update to the first
non-obsolete parent but that will be decided later.
