FreeBSD Release 4.10      
>Description:
when the root uses the "adduser" to add a new user to system ,  he has to name the user as the format of /username/,or the program  doesn't continue to realy add a user to system. It will tell you  "Please enter a username" and ask you "Enter username" again and again until you add the "/" at both ends of the username you just entered. later you have to login to the system with the username of "/username/".      
>How-To-Repeat:
simply execute the adduser program withou any parameter.
>Fix:
modify the source code of the adduser at the line of 323,the if  sentence like follow
if ($name eq $usernameregexp) 
and rewrite it as follow 
if ($name eq /$usernameregexp/)
then the bug will disappear.
