    Formats an HDL with minor error checking.
    HDL names contain two parts: prefix and suffix separated by a forward slash.
    Prefix: character string using any character in the UCS-2 character set except '/'
    Suffix: character string of any length using any character in the UCS-2 character set chosen by the registrant
    This function checks a HDL name for: prefix/suffix.  If the HDL name contains spaces, or, if it ends
    with a period or a comma, this function will emit a bad_hdl error message.
    HDL names are case-insensitive and can incorporate any printable Unicode characters so the test for spaces and
    terminal punctuation may not be technically correct but it appears, that in practice these characters are rarely
    if ever used in HDLs.
