Thanks for the fixes! Could you just squash this into one commit? Having distinct atomic history is usually a great thing, but three commits to change a total of four characters is a bit much.

@tgross35 this got me thinking: maybe we should have a command for bors to tell it that we want it to squash everything into a single commit. This is not an uncommon request we have.

glad this helped you. could you please merge it?

@crStiv could you do git rebase -i HEAD^^^ and then change the second and third line in the editor that will appear to replace pick with s (for "squash"). This will merge the three commits into one and then we can merge the pr. Happy new year!

I wish to but I use GitHub in my browser and not via my local machine

Local development does tend to be pretty necessary to help out here :) Getting started is pretty easy, we have some instructions at https://rustc-dev-guide.rust-lang.org/building/how-to-build-and-run.html.

There have been a large number of typo-fixing commits lately that require large amounts of effort to help the author "over the line" when we ask them to do small tasks like squashing commits. We do not want unnecessary churn for the compiler and none of these are user-facing. I am sorry @crStiv but I am closing this per #58619
