Get commitDistance to specified tag

[sdorof1]

I need version number in format:

major.minor.patch.build

where major.minor.patch part come from git tag, and build part should be number increment for each build. I would like to use as build-part a commitDistance but not to last tag and to first repository commit or to a specified tag, for example "0.0.0" which I tagged a first commit. Is it possible to modify versionDetails to support such global commitDistance?
