I'm not the only contributor, but I'd say its a omission. cvsexportcommit doesn't export commits. It export deltas, that is the change relative to one of the parents. It is reasonable that cvsexportcommit can "export" an empty commit by doing nothing and exiting with 0. Printing some kind of warning seems reasonable too. - robin -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
