wasmer 2.0.0: Invalid syntax in wax

[KSXGitHub]

The wax file is not a valid shell file.

Steps to reproduce

1. Go to the release page of 2.0.0 and download wasmer-linux-amd64.tar.gz.
2. Extract the archive.
3. Open bin/wax in a text editor.

Expected behavior

wax is a valid shell file:

#! /bin/bash
exec wapm execute "$@"

Actual behavior

wax's shebang is messed up:

#!/bin/bash\nwapm execute "$@"

Thank you for the bug report.

It's a difference between echo and echo -e in macOS and Linux. Let's fix that!

You can just call echo twice.

Also yes, or just do this:

echo "hello
world"

Also yes, or just do this:

echo "hello
world"

Because of indentation, it would actually be:

    # ...
    echo "hello
world"
    # ...
