This fixes comporession and uncompression of directories on MS-Windows, but also on other systems. The original code used ":" as the REGEXP of the directory entry in dired-compress-file-suffixes, which on Windows always matched any absolute file name, and can also match unusual file names on Posix hosts. This false match would cause dired-compress-file to act as if we are decompressing a directory, but use a command suitable for compression, which would fail in interesting ways. We now use a REGEXP that can never match any valid file name. * lisp/dired-aux.el (dired-compress-file-suffixes): Make the "compress directory" entry's REGEXP really fail to match any valid file name. (dired-compress-file): Adapt to the change in dired-compress-file-suffixes. (Bug#39024) (dired-compress): If the current file is a directory, or if the uncompressed file is a directory, don't remove the original from the listing, since it is left in the filesystem.
