If you try this experiment with any other text editor I think you will
see similar effects. I tried with gedit and vim and got the
corresponding effects.
Using Emacs in this case I would do C-x C-w and then navigate to the
existing directory, then one with the new name tmp2. Then I will have to
allow over-writing the copy of test.ex on disc in tmp2.
I think the text editor cannot assume that the buffer holding test.ex is
to be associated with the file in the new directory. The buffer-file
association is broken by the external renaming of the directory.
Best regards
