Hi Michalis,

This is a call of Tramp's own implementation of dired-compress-file when
default-directory is remote (ie, it has a syntax like
"/ssh:host:/path/to/file"). The reason is, that commands like "gzip"
must be executed on the remote "host" instead of the local one.

Since Tramp's implementation tramp-sh-handle-dired-compress-file is
following the implementation in dired-compress-file, and the only other
handler is in ange-ftp, I'm curious whether we shall enable support for
remote systems directly in dired-compress-file. It uses already
process-file, so it shouldn't be too hard.

Opinions?
