Paragraph breaks in word to txt conversion

There are cases where word documents show paragraph breaks with a whiteline but the resulting txt file users a single `\n` character, so there are no whitelines between paragraphs. Using `\n\n` would match the original document better.

This seemingly happens when word makes whitelines between paragraphs with styling, so there is only a single return.

It is not an acceptable solution to replace every `\n` in the output with `\n\n` as this would cause unexpected results.

No source file, test, or entry point is identified in the issue. Start by locating the Word-to-text conversion path and an input that preserves styled paragraph whitespace; done means paragraph breaks that visibly include a blank line become double newlines without changing ordinary single-line breaks.
