The problem is the following:
- eshell/sudo has the same name as /usr/bin/sudo but does something
  slightly different.
- eshell/rm has the same name as /bin/rm but does something
  slightly different.
- the combination of the two leads to "sudo rm" doing something less
  slightly different.
I don't use Eshell myself, so I'm not sure what the best way to
fix this.  Maybe it's eshell/rm that needs fixing, maybe Eshell should
change to use different name for its `sudo', or maybe the solution
should be yet different.
