>Description:
	uudeview's author makes 1023 chars as maximum header line length
	(see line 167 of uulib/uuscan.c).
	Handling this limit in the ScanHeaderLine function may skip all
	header lines after very long splitted line because of finding CR
	in the truncated string (at ptr) instead of scan source stream
	(uugen_inbuffer).
>How-To-Repeat:
	Almost any e-mail message can be used which contains very long
	(longer than 1023) header field (e.g. "To:" with many recipients)
	before fields sensitive for parsing message by uulib.
>Fix:
	Patch attached can be used in the ports project (patch prepared
	to placing it to the ports/converters/uulib/files/ directory)
