I’ve done 150 lines on what I think was a two-line diff before, and >50 on a one-line diff a few times. But I am known for my verbose commit messages. (After two years working on a twenty-odd-year-old commercial code base that had had a dozen or so people working on it constantly, I had around two thirds of the longest commit messages. My longest was something like 400 lines, but most of that was a list of affected class names or similar, on a diff of tens of thousands of lines from a mostly-automated refactoring.)

I’ve definitely also added multiple paragraphs of in-code comments to an otherwise-single-character change, where it’s an ongoing consideration rather than something that can reasonably be left in a commit message alone. Then my commit messages gets to be brief, directing you to read the added comment instead.
