merge.conflictStyle
           Specify the style in which conflicted hunks are written out
           to working tree files upon merge. The default is "merge",
           which shows a <<<<<<< conflict marker, changes made by one
           side, a ======= marker, changes made by the other side, and
           then 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.
           Defaults to true.
       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.verifySignatures
           If true, this is equivalent to the --verify-signatures
           command line option. See git-merge(1) for details.
       merge.branchdesc
           In addition to branch names, populate the log message with
           the branch description text associated with them. Defaults to
           false.
       merge.log
           In addition to branch names, populate the log message with at
           most the specified number of one-line descriptions from the
           actual commits that are being merged. Defaults to false, and
           true is a synonym for 20.
       merge.suppressDest
           By adding a glob that matches the names of integration
           branches to this multi-valued configuration variable, the
           default merge message computed for merges into these
           integration branches will omit "into <branch name>" from its
           title.
           An element with an empty value can be used to clear the list
           of globs accumulated from previous configuration entries.
           When there is no merge.suppressDest variable defined, the
           default value of master is used for backward compatibility.
       merge.renameLimit
           The number of files to consider in the exhaustive portion of
           rename detection during a merge. If not specified, defaults
           to the value of diff.renameLimit. If neither
           merge.renameLimit nor diff.renameLimit are specified,
           currently defaults to 7000. This setting has no effect if
           rename detection is turned off.
       merge.renames
           Whether Git detects renames. If set to "false", rename
           detection is disabled. If set to "true", basic rename
           detection is enabled. Defaults to the value of diff.renames.
       merge.directoryRenames
           Whether Git detects directory renames, affecting what happens
           at merge time to new files added to a directory on one side
           of history when that directory was renamed on the other side
           of history. If merge.directoryRenames is set to "false",
           directory rename detection is disabled, meaning that such new
           files will be left behind in the old directory. If set to
           "true", directory rename detection is enabled, meaning that
           such new files will be moved into the new directory. If set
           to "conflict", a conflict will be reported for such paths. If
           merge.renames is false, merge.directoryRenames is ignored and
           treated as false. Defaults to "conflict".
       merge.renormalize
           Tell Git that canonical representation of files in the
           repository has changed over time (e.g. earlier commits record
           text files with CRLF line endings, but recent ones use LF
           line endings). In such a repository, Git can convert the data
           recorded in commits to a canonical form before performing a
           merge to reduce unnecessary conflicts. For more information,
           see section "Merging branches with differing checkin/checkout
           attributes" in gitattributes(5).
       merge.stat
           Whether to print the diffstat between ORIG_HEAD and the merge
           result at the end of the merge. True by default.
       merge.autoStash
           When set to true, automatically create a temporary stash
           entry before the operation begins, and apply it after the
           operation ends. This means that you can run merge on a dirty
           worktree. However, use with care: the final stash application
           after a successful merge might result in non-trivial
           conflicts. This option can be overridden by the
           --no-autostash and --autostash options of git-merge(1).
           Defaults to false.
       merge.tool
           Controls which merge tool is used by git-mergetool(1). The
           list below shows the valid built-in values. Any other value
           is treated as a custom merge tool and requires that a
           corresponding mergetool.<tool>.cmd variable is defined.
       merge.guitool
           Controls which merge tool is used by git-mergetool(1) when
           the -g/--gui flag is specified. The list below shows the
           valid built-in values. Any other value is treated as a custom
           merge tool and requires that a corresponding
           mergetool.<guitool>.cmd variable is defined.

       merge.verbosity
           Controls the amount of output shown by the recursive merge
           strategy. Level 0 outputs nothing except a final error
           message if conflicts were detected. Level 1 outputs only
           conflicts, 2 outputs conflicts and file changes. Level 5 and
           above outputs debugging information. The default is level 2.
           Can be overridden by the GIT_MERGE_VERBOSITY environment
           variable.

       branch.<name>.mergeOptions
           Sets default options for merging into branch <name>. The
           syntax and supported options are the same as those of git
           merge, but option values containing whitespace characters are
           currently not supported.
