    scanner: allow strings starting by underscores and dots

    POSIX.1-2008 (which is simultaneously IEEE Std 1003.1-2008) says:

    "The set of characters from which portable filenames are constructed.

    A B C D E F G H I J K L M N O P Q R S T U V W X Y Z
    a b c d e f g h i j k l m n o p q r s t u v w x y z
    0 1 2 3 4 5 6 7 8 9 . _ -"

    "The <hyphen> character should not be used as the first character of a
    portable user name."

    This allows a bit more things that NAME_REGEX though, but this still
    looks fine to me.
