worktree: add --[no-]track option to the add subcommand
Currently 'git worktree add' sets up tracking branches if '<branch>' is a remote tracking branch, and doesn't set them up otherwise, as is the default for 'git branch'. This may or may not be what the user wants. Allow overriding this behaviour with a --[no-]track flag that gets passed through to 'git branch'. We already respect branch.autoSetupMerge, as 'git worktree' just calls 'git branch' internally. Signed-off-by: Thomas Gummerer <t.gummerer@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

When creating a new branch, if `<commit-ish>` is a branch,
