Should "(C) ... Gnumatic, Inc." be replaced?

[Frank H. Ellenberger]

Hi Linas,

digging in th po/ I saw in Makevars "COPYRIGHT_HOLDER = Gnumatic, Inc." and 
derived from that in [ne|rw|sv|ta].po. 

IIRC Gnumatic Inc. no longer exists, so I ask if the string - at least in 
Makevars - should be replaced and by what?

Cheers
Frank
