Re: [PATCH] branch: colorize branches checked out in a linked working tree the same way as the current branch is colorized

Jeff King [off-list ref] writes:

Alternatively, %(HEAD) could return "*" or "+" depending on whether it's
the current worktree head. That would mildly break an existing format
like:

  %(if)%(HEAD)%(then) *%(color:green)%(end)%(refname)

since it would start coloring worktree HEADs the same way. It would be
rewritten as:

  %(if:equals=*)%(HEAD)%(then)...real HEAD...
  %(else)%(if:equals=+)%(HEAD)%(then)...worktree HEAD...
  %(else)...regular ref...
  %(end)%(end)

I think that's perhaps nicer, but I'm not sure we want even such a minor
regression.

I tend to think it is not worth having to worry about it by changing
the meaning of %(HEAD) marking to save the effort to find a new
token to fill that placeholder.  Your %(worktreeHEAD) is good
enough, I would think.
