This not bug in useradd and also this is not a bug :o)
Root above is in standard behavior of getopt(), getopt_long() functions. 
>From getopt(3) man page:

DESCRIPTION
        The getopt() function parses the command line arguments. Its
        arguments argc and argv are the argument count and array as passed to
        the main() function on program invocation. An element of argv that
        starts with '-' (and is not exactly "-" or "--") is an option
        element. The characters of this element (aside from the initial '-')
        are option characters. If getopt() is called repeatedly, it returns
        successively each of the option characters from each of the option
        elements.

So correct useradd commamd line parameters for above is:

# useradd -m -d -- /home/x/-/testruebe testruebe
