Function rustdoc::clean::types::unindent_doc_fragments

fn unindent_doc_fragments(docs: &mut Vec<DocFragment>)

Removes excess indentation on comments in order for the Markdown to be parsed correctly. This is necessary because the convention for writing documentation is to provide a space between the /// or //! marker and the doc text, but Markdown is whitespace-sensitive. For example, a block of text with four-space indentation is parsed as a code block, so if we didn’t unindent comments, these list items

/// A list: /// /// - Foo /// - Bar

would be parsed as if they were in a code block, which is likely not what the user intended.
