[daip] LISTR (OPTY=GAIN) bug

[Michael Bietenholz]

  LISTR looses leading minus signs when printing out gain listings.
I think this happens when the number is exactly as wide as the field,
then it doesn't have space for the minus sign, and just drops it.

Ie. try flaggin some entries in an SN table with SNR=1.0.  LISTR will
print them out as "1000" (no minus sign) if you set FACTOR=0
(autoscale).  If you set FACTOR=10 it prints out the correct "-100"

(DEC03 AIPS)

This is where it gets lost, but the fix would have to be before this.
