I can, but I'd like someone else to state that that's their preference too. I don't see that being done in other places except `LOOP_PASS_DEBUG_RE` (and I had spent quite some time trying to understand why, was initially confused that's two arguments - didn't notice there is no comma between two string on the same line):

no line split for groups (e.g., in between `<attrs>` / `<funcdef_attrs_and_ret>` / `<func>`), only at line split due to line being too long.

split at column 81, don't think it's more than that.
