This is something I had actually thought about, but using a '_' in the %c format would not be consistent with my parsing of other format codes. However, the '+' sign is not currently used and could be applied for this purpose (ie. "%+c"). I know it isn't quite as logical as the '_', but it is more consistent from an interface point of view.

I have updated the 6.80 pre-release with this feature, and it will appear in the official versions when released.
