versions / suffixes in experimental

[Daniel Pocock <daniel@pocock.pro>]

Is there any convention for version numbers in experimental?

E.g. when uploading to backports, we add a suffix like "A.B.C~bpo70+1"
so that the system can cleanly upgrade to version A.B.C when upgrading
to the next stable release.

I have a package, version 2.2.5-5 in unstable and testing

I uploaded 2.2.5-6 and 2.2.5-7 to experimental.  Should I have given
them versions like 2.2.5-6~exp1 or something and then upload a proper
2.2.5-6 to unstable when I am happy with it?  Or should my next upload
to unstable by 2.2.5-8?  Or do I just ignore the version numbers I
uploaded to experimental and use 2.2.5-6 as the next version number for
an unstable upload, even if it doesn't contain the same things as
2.2.5-6 in experimental?
