Change the output of the likes of "git branch -l --sort=-objectsize" to show the "(HEAD detached at <hash>)" message at the start of the output. Before the compare_detached_head() function added in a preceding commit we'd emit this output as an emergent effect.
It doesn't make any sense to consider the objectsize, type or other non-attribute of the "(HEAD detached at <hash>)" message for the purposes of sorting. Let's always emit it at the top instead. The only reason it was sorted in the first place is because we're injecting it into the ref-filter machinery so builtin/branch.c doesn't need to do its own "am I detached?" detection.
