>Description:

	"b64decode -r" doesn't handle arbitary breaks in base64 encoded
	data.  White space should be accepted anywhere in a base64 encoded
	stream, not just after every chunk (4 characters).

>How-To-Repeat:

	Enter the string "VmVsb2NpdHkgUmV3YXJkcw==" with and without
	the "==" on the first line.

	% b64decode -r
	VmVsb2NpdHkgUmV3YXJkcw
	b64decode: stdin: /dev/stdout: error decoding base64 input stream
	% b64decode -r
	VmVsb2NpdHkgUmV3YXJkcw==
