marker and the original text before the `=======` marker.
merge.log::
- Whether to include summaries of merged commits in newly created
- merge commit messages. False by default.
+ 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 synoym for 20.
merge.renameLimit::
The number of files to consider when performing rename detection
during a merge; if not specified, defaults to the value of
diff.renameLimit.
+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 linkgit: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.
