Makefile: (1) include TEXINPUTS defn to point to texinfo.tex when calling tex

(2) new target as.ms (roff)
as.texinfo: sed-markers to make roff output pick up less-fancy form of
          tables and illustrations (otherwise used by info, not TeX);
          slight text chgs as workarounds for texi2roff bugs
