Potential solution

Maybe NOB_GO_REBUILD_URSELF() should imply the above Workaround (that is should be just included in nob__go_rebuild_urself). But I'm not sure about any potential pitfalls of this solution.

One downside of that "Potential solution" is that it changes the behavior of NOB_GO_REBUILD_URSELF() in a backward incompatible way. NOB_GO_REBUILD_URSELF() never modified CWD, but now it suddenly could.
