Description Martin Mosegaard CLA 2018-08-13 02:40:58 EDT 
Since Git 2.11, the default abbreviation length is no longer always 7 digits. This means that the output of a plain git describe may vary. To get consistent behavior, we can use `git describe --abbrev=N`. But that does not seem to be supported by the [DescribeCommand](http://download.eclipse.org/jgit/site/5.0.2.201807311906-r/apidocs/org/eclipse/jgit/api/DescribeCommand.html)
