accents and movable nu fixes

[Mallioch]

• Accent fixes
• Movable nu
• An iota subscript
• Added a line break that I think you probably want.

Partially because of that line break, the diff makes it look like there are more changes than there are towards the bottom.

I think I'm noticing patterns in the why of my accenting mistakes, which is good.
