In such cases, per the Coding Standards, you want an outer level of parentheses wrapping the whole right side expression. See toward the end of https://www.gnu.org/prep/standards/html_node/Formatting.html#Formatting. I see that many other places will need fixing, at some point - this rather straightforward rule is often overlooked leading to brittle formatting of many expressions, probably because it's really obvious in practice only together with Emacs, I'm not sure.

Also - this kind of stylistic nitpicking is partially personal taste - the parentheses around (__k == 0) seem definitely redundant to me, and I don't think you would find many examples of that in our code.

About the Assignement, please be patient. For example, used to be the case that when RMS was traveling couldn't process Assignments, for example. It can be slow for many reasons, it's 100% normal.
