Do you know `tramp-default-proxies-alist'? With that toy, "/sudo:host:"
can be another machine but your local one. You really don't know,
without going into deep Tramp interna.

That would be reasonable to suppress. But you don't need a special
remote test for this. Just compare the results of `file-truename', as
suggested by Eli. This shall work also for remote files automagically.

If somebody wants to apply

(copy-directory "/ssh:host:/home/user/Test" "/scp:host:/home/user/Test")

you can't suppress. Same for using different hostnames which are aliases
for the same machine, etc pp.

Best regards, Michael.
