One of this developer's primary tools to diagnose broken regression
tests is to run the test script using 'sh -x t... -i -v' to find out
*which* call *actually* demonstrates the symptom.

Hence it is pretty counterproductive if the test script behaves
differently when being run via 'sh -x', in particular when using
test_cmp or test_i18ncmp on redirected stderr.

So let's use grep instead of test_cmp/test_i18ncmp to verify that stderr
looks as expected.

In the modern world, I would probably described the problem as
"tXXXX -i -v -x", though, not "sh -x tXXXX", but they both exhibit
the same symptom.

Thanks for pointing me to -i -v -x. The introduction of the RHS -x somehow
slipped by me.

I wonder if "tXXXX -i -v -x" can be made not to contaminate the
standard error stream of the test, but that would be a larger change
we probably would not have time for 2.8 final anyway.

Agree, both on "we want to have this" and "after 2.8".

Ciao,
Dscho
