I agree this is under-documented. There is no mention of "paragraph fill" in the original paper? http://belle.sourceforge.net/doc/hughes95design.pdf
From experimentation, the semantics of fcat/fsep seems to be
- if each element is one-line: fill up current line (with
hcatorhsep) until ribbon width, then insert line break and repeat - else,
vcat
There's a specification in the code https://hackage.haskell.org/package/pretty-1.1.3.6/docs/src/Text.PrettyPrint.Annotated.HughesPJ.html#fsep
Perhaps something (from that spec, or from my comment here) could be lifted to API doc.
