Many completion functions perform hardcoded comparisons with $cword. This fails in the case where the main git command is given arguments (e.g. `git -C . bundle<TAB>` would fail to complete its subcommands).
Even _git_worktree(), which uses __git_find_on_cmdline(), could still fail. With something like `git -C add worktree move<TAB>`, the subcommand would be incorrectly identified as "add" instead of "move".
Assign $__git_subcommand_idx in __git_main(), where the git subcommand is actually found and the corresponding completion function is called. Use this variable to replace hardcoded comparisons with $cword.
