[LDM #HMK-805601]: Why is there an extraneous space (\040) behind the seqno for noaaport code?

Hi Daryl,

My my, you're deep in the weeds. :-)

I don't know why a space is put there. I didn't write the that code and it's 
not commented. I agree that the standard <http://www.nws.noaa.gov/tg/head.php> 
doesn't call for a space.

I do know that the presence or absence of a space won't affect the pqing(1) 
program. I don't know about other programs (e.g., GEMPAK decoders, McIDAS 
decoders).
