bug#44217: bug#44216: 28.0.50; Incorret during delete in Tramp: Trashing...done

[Jean Louis]

That is great if the Tramp is looking for remote `trash' command, as
there is software `trash-cli' it is named `trash' and it is
compatible with GNU rm. It is convenient.

That feature is not using the specified variable, so it is using
Freedesktop.org specified Trash location, at first invokation it was
~/.local/share/Trash and it may be configured.

In that case, when trash-directory variable is configured that is
separate from remote Trash and from Freedesktop.org and I rather
prefer specifying the trash directory myself.

The description of this variable is vague as I cannot know is it in
the context of Freedesktop.org "system's  trash", as now the remote
`trash' command is actually using such, though users could have remote
trash command to use anything; or is it in the context of being
configured through Emacs

Hide Delete By Moving To Trash: Toggle  on (non-nil)
    State : SAVED and set.
   Specifies whether to use the system’s trash can. Hide
   When non-nil, certain file deletion commands use the function
   ‘move-file-to-trash’ instead of deleting files outright.
   This includes interactive calls to ‘delete-file’ and
   ‘delete-directory’ and the Dired deletion commands.
Groups: Auto Save

As then  this settings clarify the first description.

Hide Trash Directory: Value Menu Directory: /home/data1/protected/tmp/Trash/
    State : SAVED and set.
   Directory for ‘move-file-to-trash’ to move files and directories to. More
Groups: Auto Save

In my opinion "system's trash" should be clarified. So far I
understand how it is now, it is Emacs's system's trash, it is not OS
system's trash as variable is set via Emacs.
