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 . _ -" On top of that it says: "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. For more info, see: Signed-off-by: Pablo Neira Ayuso <>
