How so?  It is currently hardcoded as such in engine.c:cmd_keyboard():

1188         switch (ch) {
1189         case KEY_ENTER:
1190         case 0x0a:
1191         case 0x0d:
1192         {
1193                 struct command * c = command_set(NULL, NULL);
1194                 c->exec(cmdbuf);
1195                 break;
1196         }
1197         case KEY_BACKSPACE:
1198         case KEY_DC:
1199         case CTRL_H:
1200                 if (cmd_len > 0) {
1201                         cmdbuf[--cmd_len] = 0;
1202                 } else
1203                         beep();
1204                 break;
1205         case 0x1b:
1206         case CTRL_G:
1207                 if (cmd_len > 0) {
1208                         cmdbuf[0] = '\0';
1209                         cmd_len = 0;
1210                 } else
1211                         command_set(NULL, NULL);
1212                 break;
1213         default:
1214                 break;
1215         }
1216 }
