git-fmt-merge-msg
(1)Produce a merge commit message
Options
5--logIn addition to branch names, populate the log message with one-line descriptions from the actual commits that are being merged. At most <n> commits from each merge parent will be used (20 if <n> is omitted). This overrides the merge.log configuration variable.
--no-logDo not list one-line descriptions from the actual commits being merged.
-m--messageUse <message> instead of the branch names for the first line of the log message. For use with --log.
--into-namePrepare the merge message as if merging to the branch <branch>, instead of the name of the real branch to which the merge is made.
-F--fileTake the list of merged objects from <file> instead of stdin.
DESCRIPTION
CONFIGURATION
merge.branchdesc
merge.log
merge.suppressDest
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.
