These should have been review comments on @pechersky's recent #2987 PR, but I was too slow.

@semorrison Why is the section pulled outside of diagonal? The bit* lemmas are defined solely for matrix n n, not arbitrary matrix m n. The numerals represent scalar multiples of one_val, which is in diagonal too.

I guess that was an oversight on my part when defining the lemmas in #2987.

@pechersky It sounds like you might need to open another PR, so I've sent you an invitation to collaborate on mathlib so you can create branches in this repo; that'll make it easier for us to see the build status of each commit.
