Thanks, I would rather not drop patches from the tree as it changes
the hashes of the tree from that point. However, in this case, I agree
that a simple revert makes things confusing, so I have done as you suggest
- v1 has been dropped from the tree.
Can you please check that the tree as of the following commit, which is
now the HEAD commit of the main branch, is correct?
