Except that Julien did mention using the latest upstream release version,
which implies that the git hash is later than the upstream release, so '+' is
correct... Here's an example with a timeline:

  |  1.2.0 is released (if packaged, version 1.2.0-1 or whatever)
  |  new Debian package version, including git changes since 1.2.0
  |  1.2.1 is released

In this example, the Debian package version could be either
1.2.0+gitYYYYMMDD.<githash>-1, which could be read as "everything in the
1.2.0 release plus all changes since, up to git hash <...> on YYYYMMDD", or
1.2.1~gitYYYYMMDD.<githash>-1, which could be read as "the 1.2.1 release
currently being prepared, as of git hash <...> on YYYYMMDD". Which you choose
would depend on whether you're packaging the release plus some fixes, or
you're packaging a preview of the next release...
