[LDM #WMK-256465]: 'Not a WMO format message' error

pqing(1) is constantly reading chunks of data into its buffer. When there's 
insufficient room in the buffer for the next chunk, then it expands the buffer.

There's nothing in a WMO message that says how big it is. Recall that the 
format for WMO messages dates from the time of teletypes.

The size of the buffer doubles when it expands, so it can end up being almost 
twice as large as the largest WMO message.
