Yep. My current convention is: --magic-open=PROG[,PROG]... So if you want to merge a gzip'd file with a bzip2'd file you can use --magic-open=gzip,bzip2 (or just --magic-open, which enables all). For each regular file it checks magic and if it looks like a type that can be handled by one of PROG it opens a PROG -d -c -f (the -f is just in case the magic was a false-positive). Of course this re-introduces findprog into sort (for find_in_path), which may not be desirable. A convention more similar to that used for --compress-program would eliminate this (and the magic-checking), but limit a given merge to files compressed with a single program.
