Really nice and I like the idea of `get-string-command-line`. Having this in the
spec files is important if you want to know what can be changed. The prepare
step is a nice way to sequence the steps and the bit I was not sure about.

Is adding this something specific? I would like to see the option directly
supported.

Thank you for the patch and the prompt response.
