[leighmcculloch]

Summary

The doc_markdown lint suggested backticks for text that is not an identifier anywhere in the code file or in the workspace.

Lint Name

doc_markdown

Reproducer

I tried this code:

#[derive(Clone, Copy, Debug, Eq, Hash, PartialEq, clap::ValueEnum)]
pub enum OutputFormat {
    /// Colorful, human-oriented console output
    Pretty,
    /// Human-oriented console output without colors
    Plain,
    /// JSONified console output
    Json,
}

I saw this happen:

error: item in documentation is missing backticks
   --> cmd\soroban-cli\src\commands\events.rs:131:9
    |
131 |     /// JSONified console output
    |         ^^^^^^^^^
    |

I expected to see this happen:

No warning, as the text "JSONified" doesn't refer to an identifier.
