case of a merge conflict.
--ff::
When the merge resolves as a fast-forward, only update the branch
pointer, without creating a merge commit. This is the default
behavior.
--no-ff::
Create a merge commit even when the merge resolves as a
fast-forward. This is the default behaviour when merging an
annotated (and possibly signed) tag that is not stored in
its natural place in 'refs/tags/' hierarchy.
--ff-only::
Refuse to merge and exit with a non-zero status unless the
current `HEAD` is already up to date or the merge can be
resolved as a fast-forward.
Specifies how a merge is handled when the merged-in history is
already a descendant of the current history. `--ff` is the
default unless merging an annotated (and possibly signed) tag
that is not stored in its natural place in the `refs/tags/`
hierarchy, in which case `--no-ff` is assumed.
+
With `--ff`, when possible resolve the merge as a fast-forward (only
update the branch pointer to match the merged branch; do not create a
merge commit). When not possible (when the merged-in history is not a
descendant of the current history), create a merge commit.
+
With `--no-ff`, create a merge commit in all cases, even when the merge
could instead be resolved as a fast-forward.
+
With `--ff-only`, resolve the merge as a fast-forward when possible.
When not possible, refuse to merge and exit with a non-zero status.
