If it isn't, why are we talking about FF and VT? They don't display as "blank" in Emacs. If the point is to close up blank lines, this is sort of like line- breaking in reverse, so only line-break characters should be deleted. Function delete-trailing-whitespace specifically states that it does not delete FF. It also doesn't delete VT. So why should delete-blank-lines delete these?
