In order to switch `clippy::uninlined_format_args` from pedantic to
style, all existing tests must not raise a warning. I did not want to
change the actual tests, so this is a relatively minor change that:
* add `#![allow(clippy::uninlined_format_args)]` where needed
* normalizes all allow/deny/warn attributes
* all allow attributes are grouped together
* sorted alphabetically
* the `clippy::*` attributes are listed separate from the other ones.
* deny and warn attributes are listed before the allowed ones
changelog: none
The only reason to use `abort_if_errors` is when the program is so broken that either:
1. later passes get confused and ICE
2. any diagnostics from later passes would be noise
This is never the case for lints, because the compiler has to be able to deal with `allow`-ed lints.
So it can continue to lint and compile even if there are lint errors.
The test program contains both conditions tested by the lint, i.e.,
a redundant continue in the `if` and `else` blocks within a loop. Maybe
splitting them out and also having a program that should *not* trigger
the lint warning is better.
