cherry-pick'ed commit, then a fast forward to this commit will
be performed.
+--allow-empty::
+ By default, cherry-picking an empty commit will fail,
+ indicating that an explicit invocation of `git commit
+ --allow-empty` is required. This option overrides that
+ behavior, allowing empty commits to be preserved automatically
+ in a cherry-pick. Note that when "--ff" is in effect, empty
+ commits that meet the "fast-forward" requirement will be kept
+ even without this option.

Use the given merge strategy. Should only be used once.
