A shortened hash value is however not truly future-proof. I recommend
using `git describe` or `git describe --contains`, as that is
unambiguous into the future and shows a related version. In case of
a748ee, that would be v2.6.35-rc1~473^2~602, which immediately tells
us that the bug has been in tarballs since 2.6.35-rc1.
