 parse_lan_channel
        Split a channel range into the "limit" channels, (e.g. P3-7 ->
        [P3, P7] also make sure that any primes are placed at the end
        (i.e. return P'5 as P5').

 Usage:
        channel = parse_lan_channel(chan)

 Argument:
        chan    string  The channel name to be parsed.

 Keyword:
        name_split      If set, then return a structure with the
                        channel type name and two numbers for the

        Fix array/scalar problem: 7/2/00; SJT
        Add special case for H3 & Name_split key: 9/2/00; SJT
        Separate out trk channels, it's just too messy otherwise:

        Modify 2-channel generator so it works for (e.g. M'3-12):
