a9c75ca by Peter Wu (peter@xxxxxxxxxxxxx):

    Avoid abort on zero-length fields
    
    Since commit v1.99.4rc0-70-g0bec885 (Remove use of sprintf for ftype
    string formatting), Wireshark aborts with "Null pointer passed to
    bytes_to_hexstr_punct()". This happened with a SSL capture where the
    ssl.handshake.extensions_padding_data had a zero length.
    
    Fix it by producing a zero-length string instead (as done by the
    previous implementation).
