Always executing a command in local user space

When I execute the command

```
(shell-command-to-string "whoami")
```

in a local buffer, I get the local user name as expected.

However, when I execute the same command on a tramp buffer (for
example editing a root file with `sudo-edit`), I get the `root`
username.

How can I ensure that my command is always executed on the local user
space regardless on the current buffer?

Commands run in the context of `default-directory`, which is good: you
can do things like run compilation on remote hosts.

If you want something to execute in a different location, you can let-
bind `default-directory` around the expression, so it points at `~/`
or some other path on your local machine.

Yep, this works!
