Alas, the file concerned (a posting I grabbed from rec.humor.funny...) has
no tab characters (at least, I couldn't spot any using cat).  On deeper
inspection, the problem affects both clear-signing and armoured signing. 

I have uploaded some files to my WWW site:
	http://www.mithlond.demon.co.uk/pjb/gnupg/testkey2.asc
	A public key.

	http://www.mithlond.demon.co.uk/pjb/gnupg/test-cs.txt
	A clear-signed file.

	http://www.mithlond.demon.co.uk/pjb/gnupg/test-as.asc
	An armoured signed file.

Can anyone determine why PGP6.x.x complains of a bad signature on these
files?

Phil.
