+'git squash-branch' [<header message>]

Preferably 'git squash-branch -m <header message>'.

Done.

+
+DESCRIPTION
+-----------
+
+`git squash-branch` is a simple helper command. It takes all the commits on the
+current branch from the 'merge_base' to HEAD, and reduces them to a single
+commit. The new commit will contain a summary of all the commits which were
+squashed, preceeded by an optional header message.
+
+Squashing branches is useful when trying to rebase-update over branches which
+were pushed to their upsteram (or committed by the 'Commit Queue'), and then
+conflicting changes landed in upstream on top of the push/commit. If you know
+that your branch was committed but linkgit:git-rebase-update[1] isn't able to
+automatically clean it, you can squash the troublesome branch before `git
+rebase-update`, and then when `git rebase-update` presents the conflict, you can
+verify that the conflict diff is what you expected (and then skip it with
+`git rebase --skip`).
+
+OPTIONS
+-------
+
+<header message>::
+	Optional message to use for the first line of the squashed commit. If omitted,
+	it defaults to "git squash commit.".
