git-fmt-merge-msg - Produce a merge commit message
Takes the list of merged objects on stdin and produces a suitable commit message to be used for the merge commit, usually to be passed as the <merge-message> argument of git merge.
This command is intended mostly for internal use by scripts automatically invoking git merge.
In 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.
Do not list one-line descriptions from the actual commits being merged.
Synonyms to --log and --no-log; these are deprecated and will be removed in the future.
Use <message> instead of the branch names for the first line of the log message. For use with --log.
Take the list of merged objects from <file> instead of stdin.
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.
Synonym to merge.log; this is deprecated and will be removed in the future.
