  Modified files:
    libexec/getty        main.c 
  Log:
  Fix some minor bugs, namely:
  
  - Initialize "rval", which would be used uninitialized
    if al or pl options were set.
  
  - Don't pass an empty string to login(1) as a user name
    (this could be triggered by entering a name and then killing it
    with backspace or ^U.)
  
  - Don't loop endlessly if the al option specifies a bogus (i.e.,
    not alphanumeric) auto-login name.
  
  - Don't pass a bogus user name to login(1) if a good name were
    entered and then killed with ^U.
  
  - Exit with status 0, not 1, on receiving an EOF character,
    since it's not a error condition.
