Wrap text to a fixed column width or unwrap it into one line. Re-flow paragraphs at 72 or 80 characters, add a prefix like > or // and split very long words.
Set the width to 80 and keep Re-wrap selected. Lines break at word boundaries.
The common convention is 72 characters per line for the body of a commit message.
Choose Unwrap. Lines inside each paragraph are joined into one line.
