[PATCH 03/14] Minor rearrangement in tui-regs.c

[Tom Tromey <tom at tromey dot com>]

This moves a couple of functions earlier in tui-regs.c.  Previously
they were in the "command" section of the file, but really they belong
in the "window implementation" section.

	* tui/tui-regs.c (tui_register_format, tui_get_register): Move
	earlier.
