Here is a testsuite addition to get some exposure to versioning.
OK to push (and add Mike to THANKS)? It'd be good if somebody
proof-read it so there are no silly typos or thinkos.
Thanks,
Ralf

Add versioning tests.
* tests/versioning.at (versioning): New file, new test.
* Makefile.am (TESTSUITE_AT): Adjust.
* THANKS: Update.
Prompted by bug report from Mike Gorchak.
