Unfortunately that version of git has a bug in its 'git archive' that was later fixed.
However, this bug causes the output to change, which breaks the entire approach of having
checksums for the archives generated by this branch.

Remember that checksums for files downloaded from GitHub would suddenly change? If we
don't want to end up in the same situation, we'll need this dependency.
