This page, as well as our man pages, say that getopt returns '?' when it encounters a bad option. Neither this web page, nor our man page, state that it is illegal to have '?' in the options string, nor do they say that -? is illegal. This is splitting a very fine hair, I'll grant... They both are silent about the issue. I personally think encouraging -? is dangerous given its potential danger, as others have pointed out, in the face of files that match the shell expresssion -? (or put as a regular expression ^-.$). Warner To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe cvs-all" in the body of the message
