It appears that many files have hardcoded references to "more":

/usr/src/grass/src/general/g.setproj/get_stp.c:170:				sprintf(buff, "more %s", Tmp_file1);
/usr/src/grass/src/general/g.setproj/get_stp.c:282:				sprintf(buff, "more %s", Tmp_file1);
/usr/src/grass/src/libes/gis/get_datum_name.c:55:	      sprintf(buff,"more %s",Tmp_file);
/usr/src/grass/src/libes/gis/get_ell_name.c:36:	      sprintf(buff,"more %s",Tmp_file);
/usr/src/grass/src/libes/gis/get_projname.c:51:	      sprintf(buff,"more %s",Tmp_file);
/usr/src/grass/src/libes/gis/gishelp.c:33:	sprintf(buffer, "more %s", file) ;
/usr/src/grass/src/libes/gis/list.c:67:	more = G_popen ("more","w");
/usr/src/grass/src/libes/gis/TESTS/try13.c:19:	more = popen ("more","w");
/usr/src/grass/src/misc/m.proj/get_stp.c:160:				sprintf(buff, "more %s", Tmp_file1);
/usr/src/grass/src/misc/m.proj/get_stp.c:262:				sprintf(buff, "more %s", Tmp_file1);
/usr/src/grass/src/raster/r.coin/cmd/inter.c:70:	sprintf(command,"more -d %s",dumpname);
/usr/src/grass/src/raster/r.combine/cmd/get_cats.c:53:	sprintf (command, "more %s", tempfile);
/usr/src/grass/src/raster/r.report/inter/run_report.c:84:    build_command(command,full,0,"|","more",nv, as_int, cat_ranges, nsteps, fp);
/usr/src/grass/src/raster/r.support/inter/check_un.c:43:    sprintf (command, "more %s", tempfile);
/usr/src/grass/src/raster/r.weight/inter/list_anal.c:91:    sprintf (command, "%s %s", print?"lpr":"more",tempfile);
/usr/src/grass/src/raster/r.weight/inter/list_cats.c:54:    sprintf (command, "more -d %s", tempfile);
/usr/src/grass/src.contrib/SCS/vector/v.report/inter/run_report.c:40:    sprintf(name,"more %s",temp_file);

I would suspect that most of the actual programs can be changed,
although more consideration needs to be given to library functions. It
seems conceivable that spawning "less" in the wrong place (e.g. from
within an interactive program) might cause problems.
