 * user who needs the info such as website URL will not read it in the command line
 * do not require first time user to press Enter (or hit RETURN) in command line to make GRASS start
 * rename function according to the part which is creating a dummy rc file
 * fixes https://trac.osgeo.org/grass/ticket/2572 for 7.x
 * see also https://trac.osgeo.org/grass/changeset/57549, https://trac.osgeo.org/grass/changeset/64345, https://trac.osgeo.org/grass/changeset/64405 and https://trac.osgeo.org/grass/changeset/64407
