I don’t understand the HEAD^ comparison sentence. It says "is the same as HEAD" followed by a weird character that looks like a combination of tilde and underscore and then says it’s the same as HEAD~3. Could this sentence be rewritten for greater clarity? When I copy/paste the character into https://www.babelstone.co.uk/Unicode/whatisit.html it says it’s a regular tilde so I don’t know why it shows up bottom aligned instead of centrally aligned. However, knowing that makes things even more confusing because that means the sentence is saying "HEAD~ is the same as HEAD~3" which…​ doesn’t make sense.
