Clearer versioning in packages.

Since Oracle (or at that time Sun) introduced the the new packaging system in Solaris Express and later Solaris 11, the version string was a little bit strange.

root@togusa:~# pkg list -H entire
entire 0.5.11-    i--

This was changed to a different output in Oracle Solaris 11.4. Now it’s versioned in a much clearer manner.

root@batou:~# pkg list -H entire
entire                                            11.4-        i--
