lines rustfmt should search for an `@generated` marker comment when

Closes 3390
`hide_parse_errors` is now deprecated, and was renamed
`show_parse_errors` to avoid confusion around the double negative
default of `hide_parse_errors=false`.
detects redundant imports that can be eliminated.
for #117772 :
In order to facilitate review and modification, split the checking code and
removing redundant imports code into two PR.
**Note** This does not add the `style_edition` config option to rustfmt.
The `StyleEdition` enum will eventually be used to allow users to
configure the `style_edition`, but for now it's added so we can
introduce the the `StyleEditionDefault` trait.
report `unused_import` for empty reexports even it is pub

An easy fix. r? `@petrochenkov`

* Inline format arguments for easier reading
Code becomes shorter and often easier to read when format args are inlined. Note that I skipped the mixed cases to make it more straightforward (could be done separatelly).
Also, there are two FIXME comments - for some reasons inlining makes format string exceed 100 char line width and crash.

```
* address feedback
This allows users to configure the maximum length of a single line
`let-else` statements. `let-else` statements that otherwise meet the
requirements to be formatted on a single line will have their divergent
`else` block formatted over multiple lines if they exceed this length.
**Note**: `single_line_let_else_max_widt` will be introduced as a stable
configuration option.
fn_args_layout is now deprecated.
This option was renamed to better communicate that it affects the layout
of parameters in function signatures and not the layout of arguments in
function calls.
Because the `fn_args_layout` is a stable option the renamed option is
also stable, however users who set `fn_args_layout` will get a warning
message letting them know that the option has been renamed.
Adds the ``nightly_only_test`` and ``stable_only_test`` attribute macros
that prevent or allow certain tests to compile on nightly and stable
respectively. This is achieved through conditionally outputting the
tests TokenStream.
If CFG_RELEASE_CHANNEL is not set, it's assumed that we're running in a
nightly environment.
To mark a test as nightly only:
#[nightly_only_test]
#[test]
fn only_run_on_nightly() {
...
}
To mark a test a stable only:
#[stable_only_test]
#[test]
fn only_run_on_stable() {
...
}
Servo has used this since forever, and it'd be useful to be able to use
rustfmt stable there so that we can use the same rustfmt version in
both Firefox and Servo.
Feel free to close this if there's any reason it shouldn't be done.
