[FFmpeg-devel] [PATCH 2/2] version.sh: Print versions based on the last git tag for release branches

[Michael Niedermayer]

release branches are detected by checking if "git" is not in RELEASE
This changes "N-64706-g2f71aeb" to "n2.3-8-g2f71aeb"
for git master theres no change

This should improve the readability of lists of versions which come from
more than 1 release branch or master + release. fate.ffmpeg.org is
one possible example
