From: Nickolai Belakovski <nbelakovski@gmail.com>
The output of git branch is modified to mark branches checkout out in a linked worktree with a "+" and color them in cyan (in contrast to the current branch, which will still be denoted with a "*" and colored in green)
This is meant to communicate to the user that the branches that are marked or colored will behave differently from other branches if the user attempts to check them out or delete them, since branches checked out in another worktree cannot be checked out or deleted.
