git revision is twice in version string

[Stefan Ritt]

The current version sting, such as

Mon Nov 13 09:24:31 2017 +0100 - commit 21d52677 on branch develop - v2.1-1513-g21d52-dirty

contains the revision "21d52677" twice. Once after the "commit" and once before the "dirty" flag. One time should be enough.

I want it like this for now. I do not fully understand "git describe" yet, and for now I want to have the git commit has explicitly present in the version string. K.O.

Fixed. K.O.
