I can say for certainty
naturally written == a script that does not contain a explicit workaround for this issue One would only add a workaround once one has been hit by a bug or knows about it and searched and found a workaround. The users time and convenience matters, we should not inconveience many people by this. > that fate and its associated scripts will not suffer from this issue, > simply because of the -nostdin flag that was added in one of the > patches (which has been applied).

It also improves > usability by fixing #2964. no heuristic works in all cases, thats the nature of heuristics for example our file format probing is all heuristics, not every file starting with "RIFFAVI" is a avi file ... if the heuristic doesnt work well enough, then it should be improved if that is possible if the bug is belived to be else where (shell, config whatever) it should be fixed there so that future default setups do not need this heuristic anymore The heuristic should be kept as long as the alternative inconveiences more people I assume that the heuristic inconveiences fewer than the alternative of nothing. Is there a reason to belive that this is not the case ?
