A shell started again by pty/ctl exec is guarded against the rename flap as a new one is

The guard that keeps a shell from taking this process's directory before
its chdir lasted only until the first shell spoke; a shell started again
in the same pane (pty/ctl exec) was asked with the old shell's word still
standing. A spawn resets it. fs.py's naming test restarts one too.
