 +(e.g. `git commit` to build a new history on top of it) still work
 +while the HEAD is detached. They update the HEAD to point at the tip
 +of the updated history without affecting any branch.  Commands that

 +current branch integrates with) obviously do not work, as there is no
 +(real) current branch to ask about in this state.
