a `>>>>>>>` marker. An alternate style, "diff3", adds a `|||||||`
marker and the original text before the `=======` marker.
+merge.defaultToUpstream::
+ If merge is called without any commit argument, merge the upstream
+ branches configured for the current branch by using their last
+ observed values stored in their remote tracking branches.
+ The values of the `branch.<current branch>.merge` that name the
+ branches at the remote named by `branch.<current branch>.remote`
+ are consulted, and then they are mapped via `remote.<remote>.fetch`
+ to their corresponding remote tracking branches, and the tips of
+ these tracking branches are merged.
+
+merge.ff::
+ By default, git does not create an extra merge commit when merging
+ a commit that is a descendant of the current commit. Instead, the
+ tip of the current branch is fast-forwarded. When set to `false`,
+ this variable tells git to create an extra merge commit in such
+ a case (equivalent to giving the `--no-ff` option from the command
+ line). When set to `only`, only such fast-forward merges are
+ allowed (equivalent to giving the `--ff-only` option from the
+ command line).

merge.log::
In addition to branch names, populate the log message with at
most the specified number of one-line descriptions from the
