Oh, good catch.  Technically "read" is not a special builtin so POSIX shells
are not supposed to do this (and Jeff's patch definitely looks right), but in
any case temporary variable settings while running a builtin are close
enough to the assignment-during-special-builtin-or-function case to
make me shiver a little. ;-)

Would something like

	(
		IFS==
		while read key value
		do
			...
		done
	)

make sense?
