Thanks, but I don't think I understand the --rm part: these commands
aren't supposed to replace the original compressed file with its
decompressed version, they are supposed to write the decompressed text
to stdout, where it will be read by Emacs and displayed, and leave the
original compressed files alone.

So I think you want "-dc", not "--rm -q".  Am I missing something?
