You're right but then "The division between streams may occur only at 
the boundaries between lexical tokens". Which means you may never have

	100 0 obj
	<< /Length 1 >>
	stream D endstream
	101 0 obj
	<< /Length 1 >>
	stream o endstream

which means in turn it is safe to append a whitespace if missing.
Ghostscript and Acrobat does - they display the source with no errors. 
And while rewriting the document and merging streams, the output is 
still valid.
