And also ells, rods, cubits, paces, furlongs, oxgangs, lots, batmans… all with subtly different regional definitions (with regions sometimes as small as one village).
People used loosely defined measurements based on things like their own body parts or how much land they guessed their ox could plow on an average day. Things like mathematical convenience or precision were not all that important; being able to measure (or estimate) without tools was.
I use interactive rebases to clean up the history of messy branches so they can be reviewed commit by commit, with each commit representing one logical unit or type of change.
Mind you, getting those wrong is a quick way to making commits disappear into nothingness. Still useful if you’re careful. (Or you can just create a second temporary branch you can fall back onto of you need up your first once.)
