The GSM Cell Broadcast dissector displays trailing \r padding characters
which would normally not be visible on a mobile.
Using the attached cb-example.pcap together with Decode User DLT 0 as
gsm_cbs wireshark displays the CBS content with the trailing \r padding
where a mobile would only display S6-19,54773% .

In the long term gsm_sms_char_7bit_unpack should perhaps be extended with
a usedfor (SMS, USSD, CB) parameter but for the time being the proposed
patch should be OK.
The patch is also applicable to the SVN trunk.
