C-Kermit (4.n) bug fix for Pro Venix

[Ozan Yigit]

Problem: C-kermit (release 4.n) "help set" or "help remote" commands
	 will core dump on Pro VENIX due to the size limitation
	 on the printf format string. (These help commands use the
	 help string as the format string, instead of printf("%s",str)).

File:	 ckusr2.c

Fix:	 Add the missing "%s" where necessary. 

Incl.:	 diff output for fixes
