.. Checking ... Ok, disjointset declares a 8.6 dependency in the code
(package require), the tests (testsNeedTcl), and the package index (if
vsatisfies guard). The latter means that it cannot be loaded into 8.5
anymore because it would not be registered at all.

However, having thought about it, having a package X declare an 8.6
dependency in the tests while still having an 8.5 dependency
declaration in code and package index, yes, that kind of mismatch and
regression I would indeed miss.

Even the `./sak.tcl validate versions` only compares package and index
version information, and ignores version information in the tests.
