Misleading error message for bad export statement

export output_format::{};
export output_styl::{};
export config;

#[doc = "The type of document to output"]
enum output_format {
    #[doc = "Markdown"]
    markdown,
    #[doc = "HTML, via markdown and pandoc"]
    pandoc_html
}

#[doc = "How to organize the output"]
enum output_style {
    #[doc = "All in a single document"]
    one_doc,
    #[doc = "Each module in its own document"]
    doc_per_mod
}

#[doc = "The configuration for this rustdoc session"]
type config = {
    output_dir: str,
    output_format: output_format,
    output_style: output_style,
    pandoc_cmd: option<str>
};

../src/rustdoc/config.rs:2:7: 2:23 error: error: undefined id output_styl in an export
../src/rustdoc/config.rs:2 export output_styl::{};

An 'id' isn't a language concept so probably shouldn't appear in the UI. Maybe 'identifier', or even 'enum' if we actually know this is checking enums.

1. Also, we don't need to write 'error' a second time.

2. And maybe also enclose the id in backticks, like in undefined id output_styl in an export.

3. Yeah, should use backticks. I happened to remove the extra 'error' in a cleanup fit yesterday.

4. The error message comes from resolve, so assigning @marijnh

5. Had to make some changes to keep the example up to date, but note that it compiles despite the fact that it exports something that doesn't exist.

   export output_format;
   export output_styl;
   export config;
   
   #[doc = "The type of document to output"]
   enum output_format {
       #[doc = "Markdown"]
       markdown,
       #[doc = "HTML, via markdown and pandoc"]
       pandoc_html
   }
   
   #[doc = "How to organize the output"]
   enum output_style {
       #[doc = "All in a single document"]
       one_doc,
       #[doc = "Each module in its own document"]
       doc_per_mod
   }
   
   #[doc = "The configuration for this rustdoc session"]
   type config = {
       output_dir: &str,
       output_format: output_format,
       output_style: output_style,
       pandoc_cmd: option<&str>
   };
   

   Compiled with rustc --lib 1908.rs.

6. Blocked on #1893 (export statements will go away altogether).

7. Since exports are on the way out, this is obsolete.
