Good afternoon:
Unless -- is explicitly given on the zdiff command line, the shell enters an
infinite loop because there is no other way to break out of the command
token while loop.
Attached is a small patch to terminate option processing when either a
filename or -- is detected on the command line.
Regards,
Joseph Parmelee
