[FFmpeg-devel] ffmpg -version gives strange version output

This happens after I compile the git ffmpeg source (baaa6d6):

./ffmpeg -version
ffmpeg version 2.1.git-tessus
built on Feb 14 2014 22:15:20 with llvm-gcc 4.2.1 (LLVM build 2336.1.00)

libpostproc    52.  3.100 / 52.  3.100

In previous versions it was shown as (just an exampe from a previous build):
ffmpeg version N-60633-g674195c-tessus

I asked this question on the #ffmpeg-devel channel as well and Michael
suggested to clone the repository into a new directory and try again.

I did that and it did not help. Maybe it has to do with the --extra-version
config option or somebody changed the build scripts, because the version.sh
script does give me an output in the format N-MMMMM-gXXXXXXX, but I couldn't
find that string anywhere in the code.

Isn't the build process supposed to write that info into a version file?
