Fix MITKRB5-SA-2007-001:

	* src/appl/telnet/telnetd/sys_term.c (start_login): Add "--"
	argument preceding username, in addition to the original patch.
	Explicitly check for leading hyphen in username.

	* src/appl/telnet/telnetd/state.c (envvarok): Check for leading
	hyphen in environment variables.  On advice from Shawn Emery, not
	using strchr() as in the original patch.
