Re: [PATCH] git-gui: use themed tk widgets with Tk 8.5

> 
> This patch enables the use of themed Tk widgets with Tk 8.5 and above.

> the Tk command 'ttk::themes'. The default on X11 is similar to the current

> Some support is included for Tk 8.6 features (themed spinbox and native
> font chooser for MacOSX and Windows).
