fn add_doc_fragment(out: &mut String, frag: &DocFragment)
Expand description
The goal of this function is to apply the DocFragment
transformation that is required when
transforming into the final Markdown, which is applying the computed indent to each line in
each doc fragment (a DocFragment
can contain multiple lines in case of #[doc = ""]
).
Note: remove the trailing newline where appropriate
