I guess the same could be done for "newins -", if you think that it is necessary (test for stdin being a terminal?). But I don't really see the point of it, since such a mistake would be noticed immediately when testing the ebuild. > The rationale for giving it a new name rather than overloading an > existing one is that some of the existing do* utilities don't take > just a single simple filename, so overloading would make the command > line somewhat convoluted. It doesn't make much sense to specify "-" as an argument for "do*", because the command would not know under which name the file should be installed. OTOH, all "new*" commands have exactly two arguments, so we could allow "-" for the first argument. Ulrich
