* Backport PR #4730 that fix issue #4689
* Test files for each Verion One and Two
* Simplify per review comment - use defer and matches!
* Changes per reviewer comments for reducing indentations

These issues were originally linked in issue 3672 and as was mentioned
in PR 3706, it's unclear which commit resolved the issue but the issue
can no longer be reproduced.
Closes 2534
The behavior described in the original issue can no longer be
reproduced. The tests show that to be the case regardless of if
`format_macro_matchers` is `true` or `false`.
* Bugfix: Now slash/start comments aren't duplicated on trait parameters.
* Removing unnecesary comment.
* Improvements: Improving the BytePos offset.
* Improvements: Improving the description of the test cases.
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.
There are some tests in the rustfmt test suite that are ignored by
default. I believe these tests are ignored because they have caused
issues with the the `rust-lang/rust` test suite.
However, we recently experienced an issue (5395) that would have been
avoided had these tests been running.
With the introduction of the new `#[rustfmt_only_ci_test]` attribute
macro we can run these tests when the `RUSTFMT_CI` environment variable
is set, which will presumably only be set during rustfmts CI runs.
When the environment variable is not set the `#[rustfmt_only_ci_test]`
will be replaced with an `#[ignore]`.

Memoizing expressions lead to cases where rustfmt's stability guarantees
were violated.
This reverts commit a37d3ab0e1c7c05f1a6410fb7ddf5539f0d030f8.
When useing `version=One` rustfmt will treat the leading `r#` as part of
the `UseSegment` used for sorting. When using `version=Two` rustfmt will
ignore the leading `r#` and only consider the name of the identifier
when sorting the `UseSegment`.

It's unclear which change fixed the `format_code_in_doc_comments=true`
issue brought up in this issue, however I'm unable to reproduce the
error on the current master.
The added test cases should serve to prevent a regression.
It's unclear which PR resolved this issue, however the behavior of

Previously, rustfmt only checked the `merge_derives` configuration value
to determine if it should merge_derives. This lead to derives being
merged even when annotated with the `rustfmt::skip` attribute.
Now, rustfmt also checks if derives are explicitly being skipped in the
current context via the `rustfmt::skip` attribute.
Fixes 5273
Previously, rustfmt searched for the start of a struct body after the
opening `{`. In most cases this works just fine, but const values can
also be defined between `{ }`, which lead to issues when rewriting the
struct body.
Now, rustfmt will search for the `{` after the generic argument list to
guarantee that the `{` it finds is the start of the struct body.
Fixes 5167
When ``a.rs`` and ``a/mod.rs`` are both present we would emit an error
message telling the user that the module couldn't be found. However,
this behavior is misleading because we're dealing with an ambiguous
module path, not a "file not found" error.
Is the file ``a.rs`` or is it ``a/mod.rs``? Rustfmt can't decide, and
the user needs to resolve this ambiguity themselves.
Now, the error message displayed to the user is in line with what they
would see if they went to compile their code with these conflicting
module names.
