Yes.  I'm still not convinced trying to specify fragments of
stream files is a good idea at all but, if it is to be done,
let's do it with a new command and very clearly-specified
semantics.  Remember that, if transfers are done in TYPE I, 

	-- not only can one have any of the usual
	line-separation characters, but one can have other sorts
	of record markers or length-delimited lines or blocks.
	
	-- if Unicode is being sent consistent with the base
	spec), one gets internal storage forms (often UTF-16LE
	or UTF-16BE) not only UTF-8, and certainly does not get
	one octet per character.

So specifying fragments clearly is not a trivial piece of work
unless the new command also requires a new file STRUcture
variation.
