If the concern here is about duplication for the calling-strings, maybe
it would be preferable to use a macro rather than a helper function. I
agree with your reasoning from discussion on v3 of the patch that it's
more elegant to keep the icd file contents groups together.
Although maybe it would be preferable to setup a single multiline-string
and use sprintf or something? That seems simplest from a readability
standpoint.
