| -a, \--append:: |
| Append ref names and object names of fetched refs to the |
| existing contents of `.git/FETCH_HEAD`. Without this |
| option old data in `.git/FETCH_HEAD` will be overwritten. |
| |
| -f, \--force:: |
| |
| -t, \--tags:: |
| By default, the git core utilities will not fetch and store |
| tags under the same name as the remote repository; ask it |
| to do so using `--tags`. |
| |
| -u, \--update-head-ok:: |
| By default `git-fetch` refuses to update the head which |
| corresponds to the current branch. This flag disables the |
| check. Note that fetching into the current branch will not |
| update the index and working directory, so use it with care. |
