dispatch: defer environment variable resolution in alias commands (BC) Before this patch, if there are environment variables in an alias command, they will be expanded immediately when we first see the alias. This will cause issues with chg, because environment variable updates will not propagate to expanded arguments. This patch makes "args" of "cmdalias" a property that will be calculated every time when accessed.
