Builds on previous commit.
Note: Getting the project version still pases --tags so still works with plain
tags, to keep compatibility for existing projects
In some cases gen_version_specific_includes.py would fail to find a branch/tag name for a commit
and would fall back to using commit SHA-1.
This should never happen in docs that should be published as we use the branch/tag name to generate
example commands for our users. E.g. "git clone -b $branch_name"
