Depends on how involved the addition of the tests that actually use
the helper, but in general it would be a good idea to add it in the
first patch that actually uses it.  Unused code added in a separate
patch will not point at that patch when bisecting, if that unused
code was broken from the beginning (not that I see anything
immediately broken in the code the following adds).

These days we should use write_script to do this kind of thing, I
think.
