bug in generation of help.h
When bootstrapping 3.13 builders the build of apk-tools ended up hanging, and the next day the disk was full. When investigating where the disk usage went it turned out that the majority of the disk usage was taken by aports/main/apk-tools/src/apk-tools-v2.12.0/src/help.h:
# du -sh help.h
69.8G help.h
# head help.h
