Test-Tooling, no direct code impact (so nothing for me to test).

One actual code change sneaked in here (bring in a "const") - it
might actually be bringing *back* that const (the diff line looks
familiar from one of the last CVE patches which had some conflicts
with a patch that introduced consts there).  But the change is
trivial & correct.

Your patch has been applied to the master branch.
