Issues with doc/scripts/GMT_movie_progress.sh on Windows

[maxrjones]

Description of the problem

This test often fails with something like:

Set GMT_SESSION_NAME = 8917
GPL Ghostscript 9.50: Unrecoverable error, exit code 1

When the failing tests are rerun, it fails twice more because the temporary assembly directory (here /tmp/junk) only gets deleted when the commands all run successfully:

 The following tests FAILED:
	126 - doc/scripts/GMT_movie_progress.sh (Failed)

Is there a way to proceed with the cleanup if -Z is set but the script does not execute successfully?

Yes, we should clean up that directory before exiting. I will see if I can add that code to the Return macro.
Another improvement to movie and batch would be to allow for a random working directory. To be backwards compatible we will need a modifier I think, maybe -W+t for temporary directory? This will create things like /tmp/tmp_movie_123456 and I believe this TMPDIR will need to be written to the parameter scripts.
