Well, this is set this way for decades. I don't remember the datails;
likely it was used also for other cases than just local encoding/
decoding. And don't forget, Tramp has carried a lot of compat code, back
to Emacs 21 and XEmacs. Maybe it was not possible to trust on `w32-shell-name'.
This compat code has been removed recently. So it is applicable indeed,
to use `w32-shell-name'. I've committed a patch to master, doing this. I
don't know, whether the setting for `tramp-encoding-command-switch' is
OK, 'tho.
As usual, I cannot test it for w32. Let's see, whether we get reports :-)

Agreed. This fits perfectly to the Tramp cleanup, I have applied back in
January.
Best regards, Michael.
