option old data in `.git/FETCH_HEAD` will be overwritten.
-f, \--force::
+ When `git-fetch` is used with `<rbranch>:<lbranch>`
+ refspec, it refuses to update the local branch
+ `<lbranch>` unless the remote branch `<rbranch>` it
+ fetches is a descendant of `<lbranch>`. This option
+ overrides that check.
+
+\--no-tags::
+ By default, `git-fetch` fetches tags that point at
+ objects that are downloaded from the remote repository
+ and stores them locally. This option disables this
+ automatic tag following.
-t, \--tags::
+ Most of the tags are fetched automatically as branch
+ heads are downloaded, but tags that do not point at
+ objects reachable from the branch heads that are being
+ tracked will not be fetched by this mechanism. This
+ flag lets all tags and their associated objects be
+ downloaded.
+
+-k, \--keep::
+ Keep downloaded pack.
-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.
