There is no "refusing to move main worktree location" error message
issued? Perhaps it is done elsewhere and this is merely for an
added safety (in which case it is OK)?

Does anybody set "ret" to anything but 0 in this function? It is
unclear what the return value from this function means in the first
place, but I am assuming that this is meant to follow the usual
convention of 0 for success and negative for error, in which case
the "return early if this is the primary one" would want to return
-1, I guess.
