    pfctl: odd condition/test in PF lexer
    
    This commit rectifies earlier change:
    
        in the lex... even inside quotes, a \ followed by space or tab should
        expand to space or tab, and a \ followed by newline should be ignored
        (as a line continuation).  compatible with the needs of hoststated
        (which has the most strict quoted string requirements), and ifstated
        (where one commonly does line continuations in strings).
