2 Append ref names and object names of fetched refs to the
3 existing contents of `.git/FETCH_HEAD`. Without this
4 option old data in `.git/FETCH_HEAD` will be overwritten.
9 By default, the git core utilities will not fetch and store
10 tags under the same name as the remote repository; ask it
11 to do so using `--tags`. Using this option will bound the
12 list of objects pulled to the remote tags. Commits in branches
13 beyond the tags will be ignored.
15 -u, \--update-head-ok::
16 By default `git-fetch` refuses to update the head which
17 corresponds to the current branch. This flag disables the
18 check. Note that fetching into the current branch will not
19 update the index and working directory, so use it with care.
