[Xen-devel] [PATCH] CODING_STYLE: discourage use of underscores where alternatives exist

["Jan Beulich" <JBeulich@xxxxxxxx>]

Underscores commonly require two keypresses while hyphen / dash requires
just one, and the visual separation effect of both is basically the same.

+While for identifiers underscores are unavoidable when a visual
+separator beween name components is wanted, in other cases, where a
