I don't understand why everybody is so afraid of an epoch, but ok.

So the epoch is not really part of the version number, it is just there for
"sorting"?

ok

If this can't go into policy, then I hope it will go into the wiki or a
packaging best-practices or so.

So what should I have done intially and what should I do now?

I should have uploaded the package as 1.0.51-12 even though I uploaded a
(new) orig.tar.gz?

Now I should upload it as 1:1.0.51-12 and be done with it?

No renaming of the orig.tar to 1.0.51+really1.0.51 neccessary?

thanks,
Christian
