That's the idea of eshell's built-ins.

Again, it does what you could expect from *eshell*. If you do not want
this behaviour, you could use *shell*. Or you could mask the built-in by
prepending a "*" to the command, as described.

The question is whether a command being an argument of "sudo" shall
still behave like other eshell commands. This is not only true for "rm"
(being `eshell/rm'), but for all commands which could be a valid Lisp
command.
