+  - Unless only one batch interpreter is available, there is no default

+    `--batch` but not `--batch-interpreter`, GIMP will output an error
+    message and will list the available interpreters.
+  - GIMP will stop running the batch commands as soon as one command
+    fails (it won't try the following ones).
+  - A new `--quit` option allows you to quit GIMP immediately after
+    running the batch commands.
+  - If `--quit` is set and batch commands are run, the GIMP binary exit
+    code will propagate errors from any batch failure. Exit codes are
+    taken from command Linux error codes: 0 for success, 69 for service
+    unavailable (e.g. setting a non-existing interpreter name), 64 for
