ren: end-of-sentence spacing when followed by font/size changes The adj_nonl() command was added to prevent newlines for lines containing only commands that do not print anything (like font or size changes). This patch makes sure render() does not call adj_nonl() unnecessarily; otherwise, it may inhibit the insertion of a space after end-of-sentence characters (when followed by a line break starting with \f escape sequence).
