(I'm going through old bug reports that unfortunately weren't resolved at the time.) If Emacs had code to automatically recognise compressed data, I guess tar-mode could decompress the buffer before it started working on it. (Does Emacs have that? I guess we could add stuff to `magic-fallback-mode-alist' or something in that region...) But I think the question is -- do we want to support this? I'm not quite sure -- it would be pretty unusual for a mode to do something like this, and it's not clear what the semantics should be. That is, if we're saving the tar buffer afterwards, should it be compressed or not? Either option would surprise somebody. And finally -- is this a thing that actually exists in the wild? I don't think I've ever seen a compressed tar file that didn't have a name that indicated how it was compressed. So due to both the unclear semantics and that I doubt the utility, I'm inclined to close this as a "wontfix". Anybody got any opinions? --=20 (domestic pets only, the antidote for overdose, milk.) bloggy blog: http://lars.ingebrigtsen.no
