Describe the bug

Executing a cell with the following code creates very long output.

#r "nuget: FsCheck"

open FsCheck

let revRevIsOrig (xs:list<int>) = List.rev(List.rev xs) = xs
Check.Quick revRevIsOrig

It looks like this is probably a symptom of the same issue as #799 (along with #879 and #951). FsCheck has a few places that format together a long sequence of mostly empty strings to get their desired output, but each of those "%s" formats is getting wrapped in newlines due to #799.
