* Makefile.in: (REFEDITS) new var to control whether PS or CM

	fonts and whether US or A4 paper for GDB refcard; (refcard.dvi)
	collect sed edits if any, apply to refcard before formatting;
	(refcard.ps) stop implying PS fonts if PS output requested;
	(lrefcard.ps) delete extra target for variant PS fonts

	* refcard.tex: parametrize papersize dependent info, collect
	  in easily replaced spot

	* a4rc.sed: new file, edits to refcard for A4 paper
