GIT-VERSION-GEN improvements

As the subject says, this patch series makes some improvements to the GIT-VERSION-GEN script. In particular, it introduces the use of "git describe --dirty", and fixes some minor style issues.

v3 adds two more patches to v2.

Mathias Lafeldt (3):
GIT-VERSION-GEN: make use of git describe --dirty
GIT-VERSION-GEN: tweak processing of version file
GIT-VERSION-GEN: style nitpicks
