sure, that's a good rule.

First, let me mention what I see as the main disadvantage of your
patch: config.status is less readable with all those expansions.
And two two levels of here-documents make status.m4 difficult to
read, so looking into a generated config.status is often useful.

``something nicer'' I would like to add a check which would rule out
shells with this bugs from the ``better shell'' selection.
If I understand it correctly, there is always another usable shell on
the affected machines.

I'll prepare a patch later.
