Generally, I write papers and such in a text editor with hard wrapping, like nano, and then transfer them to LibreOffice for formatting. So I go from newline after X columns and a blank line between paragraphs to long lines with a single newline between paragraphs. The simplest algorithm would be to remove all newlines except double newlines (and convert those to single). If -s was specified, we would only remove newlines after spaces and tabs (or unless there was no space in that line). Finally, if -w was specified, we would re-wrap at that width.
