*	Implement the roff(7) .shift and .return requests,	Ingo Schwarze	2018-08-23	1	-0/+7
	for example used by groff_hdtbl(7) and groff_mom(7). Also correctly interpolate arguments during nested macro execution even after .shift and .return, implemented using a stack of argument arrays. Note that only read.c, but not roff.c can detect the end of a macro execution, and the existence of .shift implies that arguments cannot be interpolated up front, so unfortunately, this includes a partial revert of roff.c rev. 1.337, moving argument interpolation back into the function roff_res().
