83d1d9aa14 normalize_doc_attributes: remove leading whitespace from the doc comment opener 
Remove possible whitespace from the `CommentStyle::opener()` so that the literal itself has control over the comment's leading spaces.

This is most useful for tools, such as bindgen, to allow for example: machine-readable comments with precise syntax rules, or idempotently round-tripping between the proc-macro API and rustfmt.

fix alignment of a struct's fields with the visual style 
- rewrite_with_alignment was called from the expr module with the wrong
  shape that missed the extra offset needed for the visual style
- rewrite_with_alignment was indenting the given shape although that
  should have been the caller's responsability

The method trim_left_preserve_layout didn't handle tabs properly. 
This is fixed by taking the method macros::indent_macro_snippet which
essentially does the same: it indents a paragraph while preserving the
layout.

missed-spans: Fix bogus check. 
I don't really know what it's trying to do, but forgetting about everything
you've seen before when you see whitespace followed by a semicolon doesn't look
right to me, and absolutely no tests were hitting that.

This check was introduced in 5ecdd072d6, however
it was wrong even at that point, and now rustfmt still passes that test,
regardless of macro name.

Fixes #3154.

Try to fix formatting failures on Windows (issue #2810)

00a20bceff Fix formatting failures on Windows 
When newline_style is set to Windows, an empty line inside of a macro
results in `\r` being passed to the `fold()` in `MacroBranch::rewrite()`.

`\r` is technically not an empty string, so we try to indent it, leaving
trailing whitespaces behind, even though that was not intended
(as far as I can see).

This commit replaces the `!l.is_empty()` check with calling
`is_empty_line()`, since trying to indent any whitespace-only string
will probably result in problematic trailing whitespaces.

Fixes: #2810

Fix handling of code that is annotated with rustfmt::skip. 
A rustfmt::skip'ed block is indented although original lines are
returned. In order to resolve this, the leading whitespaces are trimmed
on each line while retaining the layout; this leaves the skipped code
to be indented as necessary by the caller.

65ae0b9a09 Change enum align semantics to care about absolute length, rather than difference. 
If we're only aligning enum discriminants that are "not too far apart
(length-wise)", then this works really well for enums with
consistently-long or consistently-short idents, but not for the mixed
ones.
However, consistently-long idents is somewhate of an uncommon case and
overlong idents may be allowed to be formatted suboptimally if that
makes mixed-length idents work better (and it does in this case).

lists: Detect block comment by starting from the end. 
The issue with the current code is that comments are collapsed, so comments like
the one from the test end up in a string like:

```
"// this is a single line comment\n/* block = */"
```

I chose to fix it by detecting whether we're in a block comment starting from
the end instead, and tested a single-line comment ended in `*/` just for sanity,
ensuring line breaks are not removed in that case, which would break the
formatting.

The right fix eventually is probably to lex the comments properly, but this does
the work for now, I guess :)

fix the identification of a block comment. 
Block comments like below were not properly supported:

    /*

     */

because of the line that didn't start with a star.
