I've found and fixed the bug. sdiff uses diff which returns EXIT_FAILURE
if the files are different. However, sdiff bombs with this wrong
error message when diff returns EXIT_FAILURE. Anyway, *after* fixing
the bug I googled for it and found that Paul Eggert fixed the bug
about a year ago. Still there's no fixed version available...

I've attached my version of the bugfix.
