Dave Robbins asked,

I'm going to take "not beginning with a header" to mean "not in the head";
i.e., in the body, and "[a line] not beginning with a blank line" to mean
"not beginning with a space."
# brackets enclose caret,space,tab,greater-than,less-than,colon,pipe
:0Bbfw # seventy-nine dots on continuation line
* ^[^ ><:|]\

You could also use fmt (with whatever options you like) to reformat the
entire body instead of fold (which works on individual lines).
