Change close_and_rename() to read_only_bottom_close_and_rename()

All users of close_and_rename() were printing out the appropriate "ex: set ro:"
string to the file handle immediately before closing it. So move that into
the common function and rename it to reflect what it now does. [Except
overload.pl, which should have been, given that it calls read_only_top()]

Print a newline above the "ex: set ro:" line. This removes many newlines from
the regen scripts, but does add newlines to a couple of generated files.
