I have a very long line of text (8000 characters). I would like to format this nicely so it splits across multiple lines in a block. Where the line breaks occurs does not matter for this purpose.
aaaaaaaa bbbbbbbb cccccccc dddddddd
I chose eight characters before a line-break, but that number does not matter either- it could be 8 or 80.
fill-paragraph does not seem to work for me- nothing happens.
N.B. I'm not asking about Line Wrapping, or how the text is displayed.
