I feel you ! <| sep |> What . I ' m sorry but I ' m starting to doubt that your reading comprehension . Saracs might be MG 42 s , literally . That I do not know as I ' m not much into Yugo armaments . But MG 3 s have so much more done to them than rechambering . They have a heavier bolt , almost twice the weight and thus reduces the ROF and chrome lined barrel plus some more little gimmicks . But many MG 42 s were converted into MG 3 s . <| sep |> Not claiming to speak for OP , but one reason people post questions to remacs and SO and other places and not the bug tracker or mailing list , is that they ' re not primarily worried about getting the bug fixed they ' re worried about working around it so that they can continue doing whatever they were doing . This is extraordinarily common , especially with such complex software like Emacs just look at how extension support like package . el emerged when people for whatever reasons couldn ' t get their patches into Emacs proper . Then ELPA emerged , and when even that wasn ' t enough , MELPA with bleeding edge packages sprung forward . Today , I ' d argue most of the Emacs development is being done in packages on GitHub rather than on the Emacs mailing list . I think it ' s a part of Emacs culture by now fix your problem , write a package to do it if necessary , and don ' t worry too much about sending bug reports or patches upstream . The value of sharing changes with others diminishes when everyone is using Emacs for different things , in different ways , and with different configs anyway .
