Not Necessarily a Bug (oh, yes it is!)

Some version of the Bourne shell (I think it was the one that results from
applying all the changes Arnold Robbins posted) specifically checks for
"rsh" being the basename of argv[0].  Any other check is incorrect; the
"if (strchr(argv[0], 'r') != NULL)" check is bogus and the result of
laziness.  The fix is straightforward.
