Updating that function with those compressors is useful and related
this wish to have "gzip" also customizable. As dired-x supports
decompressing various files but user have no possibility to customize
the compressor command.
There are also pbzip2, pigz, pixz, pixz that offer parallel
compression that could be included in future.

In the function: dired-compress-file there is hard coded gzip as
compressor:
(dired-check-process (concat "Compressing " file)
"gzip" "-f" file))
It would be useful to have customization as there are various other
compressors that are often used to distribute files such as these, and
all of them supprot -f option:
- bzip2
- xz
- lzip
- there may be others
Customization option could be called dired-compress-command or
similar and it could default to gzip
(defcustom dired-compress-command "gzip"
"Default compressing command for dired. The commpressing
command shall support the option `-f' to force overwriting the file"
:type 'string
:group 'dired)
Then the part here in the function `dired-compress-file' can be changed to:
(dired-check-process (concat "Compressing " file)
dired-compress-command "-f" file))
Thanks,
Jean Louis
