[PATCH]: Fix tui register window

[Stephane Carrez <Stephane dot Carrez at worldnet dot fr>]

Hi!

I've committed the following patch that fixes the display in the TUI
register window:

 - the register formatting uses 16 characters to print the register name
   the effect is that the `<name> <hex> <dec>' string is too big to fit
   in the register window and it is truncated.  The patch reduces to 8 chars
   the name of register (until some best solution is found).

 - it's necessary to touch the window when the register has changed.

	* tuiRegs.c (tuiDisplayRegistersFrom): Call touchwin.
	(_tuiRegisterFormat): Reduce size of format result.
