Shellcheck flags two issues in ppp_common.sh. As we are aiming
for new tests to be shellcheck-clean I'd appreciate it if you could
look into this.

My suggestion is that SC2148 can be addressed by adding #!/bin/bash
to the top of the file.

And SC2153 can be suppressed using # shellcheck disable=SC2153

Please add a trailing " \" to the line above,
so it won't need to be modified if another item
is added after it on a new line.
