* sh-tdep.c (sh_do_pseudo_register): Indent properly. Call
 	do_dr_register_info() only for DR registers.
	(sh_sh4_register_name): Add comments with numbers.
	(_initialize_sh_tdep): Move assignment to disassemble printing
 	function from here...
	(sh_gdbarch_init):...to here. Move some more general settings to
 	before the architecture is recognized.
