cfg_attr based modification of ticks is split into two code chunks

[drahnr]

Describe the bug

Some code blocks are not ignored as block.

To Reproduce

Steps to reproduce the behaviour:

1. A file containing

/// # Example
///
#[cfg_attr(unix, doc = "```no_run")]
#[cfg_attr(not(unix), doc = "```ignore")]
/// use std::path::Path;
/// assert_eq!(Path::new("./is_a_directory/").is_dir(), true);
/// ```

3. Run cargo spellcheck ...
4. ...

Expected behavior

Ignore the code

In rust (a39ac5ae175e0f9f910b1800a430b488ec0f2105) there are a handful of instances of the pattern:

library/std/src/path.rs:    #[cfg_attr(unix, doc = "```no_run")]
library/std/src/path.rs:    #[cfg_attr(not(unix), doc = "```ignore")]
library/std/src/fs.rs:    #[cfg_attr(unix, doc = "```no_run")]
library/std/src/fs.rs:    #[cfg_attr(not(unix), doc = "```ignore")]
library/std/src/os/unix/net/stream.rs:    #[cfg_attr(any(target_os = "android", target_os = "linux"), doc = "```no_run")]
