* Original version majorly reworked for SUSv3 compliance, bug fixes, and
* size optimizations. Changes include:
* 1) Now correctly distinguishes between errors and actual file differences.
* 2) Proper handling of '-' args.
* 3) Actual error checking of i/o.
* 4) Accept SUSv3 -l option. Note that we use the slightly nicer gnu format
* in the '-l' case.
