What this means is that you can discard your temporary commits
and merges by switching back to an existing branch (e.g. `git
checkout master`), and a later `git prune` or `git gc` would
garbage-collect them.

the reflog for HEAD where you were, e.g.
The command would refuse to switch back to make sure that you do
not discard your temporary state by mistake when your detached
HEAD is not pointed at by any existing ref. If you did want to
save your state (e.g. "I was interested in the fifth commit from
the top of 'master' branch", or "I made two commits to fix minor
bugs while on a detached HEAD" -- and if you do not want to lose
these facts), you can create a new branch and switch to it with
`git checkout -b newbranch` so that you can keep building on
that state, or tag it first so that you can come back to it
later and switch to the branch you wanted to switch to with `git
tag that_state; git checkout master`. On the other hand, if you
did want to discard the temporary state, you can give `-f`
option (e.g. `git checkout -f master`) to override this
behaviour.
