Let me see if I understand correctly:

I release my dbf package as 1.3.

Somebody at Debian fixes a bug, and rather than wait for me to release the next 
version just slap a local tag on it --
so now there is:

  - 1.3  (mine)
  - 1.3+debian1

At this point, a non-debian user asking for 1.3 will get mine, whereas a debian 
user would get the 1.3+debian1 version.
 Correct?  Plus, a debian user asking for 1.4 would also get 1.3+debian1?

Now, I fix that bug plus a few more, and make a 1.4 release.  A non-debian user 
would get my 1.4 release.  Which version
will a debian user get?

  - 1.3+debian1 ?
  - 1.4 ?

If my 1.4 does not sort higher than a 1.3+blahblah anything, that's not good.
