"git branch -h" incorrectly said "--track[=direct|inherit]", implying that "--trackinherit" is a valid option, which has been corrected. source: <3de40324bea6a1dd9bca2654721471e3809e87d8.1642538935.git.steadmon@google.com> source: <c3c26192-aee9-185a-e559-b8735139e49c@web.de> * js/branch-track-inherit: branch,checkout: fix --track documentation
