Format file references as markdown links

When referencing files in your output, always format them as markdown links. Use the GitHub-style #L fragment for line numbers.

Format

With a line number:

[filename.el:42](relative/path/to/filename.el#L42)

With a line range:

[filename.el:42-50](relative/path/to/filename.el#L42-L50)

Without a line number:

[filename.el](relative/path/to/filename.el)

Important

• The link text uses : for line numbers (e.g., filename.el:42).
• The URL uses #L for line numbers (e.g., filename.el#L42).
• For ranges, the link text uses - (e.g., filename.el:42-50) and the URL uses -L (e.g., filename.el#L42-L50).
• The range must appear in both the link text and the URL.

Do NOT do this:

[filename.el#L42-L50](filename.el#L42)

Rules

• Use paths relative to the project root.
• Include line numbers when they are relevant (e.g., error locations, function definitions, modified lines).
• Use line ranges when referring to a block of code.
• The link text should be the filename (or relative path if needed for clarity) followed by the line number.
