In set_work_tree(), variable rel needs to be reinitialized to NULL on every call (it should not be static). Make sure the incoming dir variable is not too long before copying to the temporary buffer, and make sure chdir to the resulting directory succeeds. This was spotted and fixed by Alex and Johannes in a handful patch exchanges. Here is the final version.
