git history: the best thing in Git 2.54

Git 2.54 dropped yesterday. 137 contributors, 66 of them first-timers. But the thing I keep thinking about is a small experimental command called git history.

It does two things. git history reword lets you fix a commit message and rewrites everything downstream. git history split lets you chop a commit into pieces with the same hunk-picker from git add -p. Neither operation touches your working tree or index.
