Most of the places I’ve worked I’d have been told to get rid of the cursing before checking something in. But, my own personal codebase has tons of this sort of thing.

But, aside from the cursing, these actually look like excellent comments. Comments should warn you when the code isn’t what you might expect. These are excellent from that point of view. If this is what a random sampling of the comments in the codebase looks like, it is probably a very well commented codebase.
