test release numbering

[David Timms]

We've probably all noticed that the test releases are marked as version:
4.90, 4.91 etc.

It would seem more logical to me for the last part of number to also be 
the test number. This would mean:
4.91 5test1
4.92 5test2
4.93 5test3
..
4.105 5test15
I don't imagine that such a change would be massive, but would improve 
the numbering for the non c programmer who actually uses fedora...
