The following command was used to collect new authors, improvements
are welcomed. It excludes authors that only touched po*
directories. I'm adding it to the commit message to have it stored
somewhere until next time it is needed.

find -maxdepth 1 | grep -v po | grep -v "^.$" | \
xargs git --no-pager log --pretty=format:%an GIMP_2_7_0..HEAD -- | \
sort | uniq > authors-temp.txt
