[PATCH] verify-tag: also grok CR/LFs in the tag signature

On some people's favorite platform, gpg outputs signatures
with CR/LF line endings.  So verify-tag has to play nice with
them.

	I just pushed a fix to 4msysgit.git which prevents the generation 
	of such tag signatures, but it's always better to be a little more 
	graceful.

	Note that the match less strict than before, but if you really 
	have to start a line in a signed tag with that magic BEGIN 
	PGP SIGNATURE string, you cannot be helped anyway.
