It's reasonable to want to, but in the current implementation this causes multiple problems. - All the `rmake.rs` files are formatted every time even when they haven't changed. This is because they get whitelisted unconditionally in the `OverrideBuilder`, before the changed files get added. - The way `OverrideBuilder` works, if any files gets whitelisted then no unmentioned files will get traversed. This is surprising, and means that the `rmake.rs` entries broke the use of explicit paths to `x fmt`, and also broke `GITHUB_ACTIONS=true git check --fmt`. The commit removes the `rmake.rs` entries, fixes the formatting of a couple of files that were misformatted (not previously caught due to the `GITHUB_ACTIONS` breakage), and bans `!`-prefixed entries in `rustfmt.toml` because they cause all these problems.
