In terms of implementation, they both do exactly the same thing:

lib/raster/loc_io.c:

	const char *ftfont = getenv("GRASS_FT_FONT");
	...
	const char *font = getenv("GRASS_FONT");
	...
	if (ftfont)
		R_font(ftfont);
	else if (font)
		R_font(font);
	else
		R_font("romans");

display/d.mon/pgms/select.c:

	const char *ftfont = getenv("GRASS_FT_FONT");
	...
	const char *font = getenv("GRASS_FONT");
	...
	R_font((ftfont ? ftfont : (font ? font : "romans")));

R_font() gets passed the value of whichever variable is defined; using
GRASS_FT_FONT=romans would work. OTOH, the _FT_ is misleading, so that
one should probably go.
