git-fmt-merge-msg - Produce a merge commit message
git fmt-merge-msg [-m <message>] [--into-name <branch>] [--log[=<n>] | --no-log]
git fmt-merge-msg [-m <message>] [--log[=<n>] | --no-log] -F <file>
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.
--log[=<n>]
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.
--no-log
Do not list one-line descriptions from the actual commits
being merged.
--[no-]summary
Synonyms to --log and --no-log; these are deprecated and
will be removed in the future.
-m <message>, --message <message>
Use <message> instead of the branch names for the
first line of the log message. For use with --log.
--into-name <branch>
Prepare 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 <file>, --file <file>
Take the list of merged objects from <file> instead
of stdin.
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.summary
Synonym to merge.log; this is deprecated and will
be removed in the future.
$ git fetch origin master
$ git fmt-merge-msg --log <$GIT_DIR/FETCH_HEAD

branch from the "origin" remote.
