evolve: add test to demonstrate a bug when no active topic
Added test shows that the logic to find the destination for
`hg up` in the case when "working directory parent has a topic
but wdir has no active topic" is buggy.
This will be fixed in next patch.
#!/bin/sh
. $TESTDIR/testlib/pythonpath.sh
# This file holds logic that is used in many tests.
# It can be called in a test like this:
# $ . "$TESTDIR/testlib/topic_setup.sh"
# Enable obsolete markers and enable extensions
