It is. But there's a problem with "compressing" directories: Emacs 26.1 introduced an ambiguity, because 'Z' on a directory produces a .tar.gz archive out of its files, but 'Z' on a .tar.gz file can either uncompress to produce a .tar file or unpack all the files into a directory. > It's fine to have another key that unpacks a tar, or > even another key that both uncompresses and unpacks. Then someone will complain that 'Z' on a directory is not its own inverse. > BTW, I don't see this change called out in NEWS for > Emacs 26. Is it there and I just missed it? It wasn't announced, and the manual wasn't updated to say what 'Z' does in a directory. Shame on us. > Compress or uncompress marked (or next prefix argument) files. > A prefix argument ARG specifies files to use instead of marked. > An integer means use the next ARG files (previous -ARG, if < 0). > `C-u': Use the current file (whether or not any are marked). > `C-u C-u': Use all files in Dired, except directories. > `C-u C-u C-u': Use all files and directories, except `.' and `..'. > `C-u C-u C-u C-u': Use all files and all directories. Is "C-u 0' available?
