If the source is available, the compiler could be tweaked to obey a protocol, putting delimiters around collapsable output (possibly non-printing control sequences??)

I believe both emacs and vim have folding submodes which operate based on comments containing {{{ / }}} to bracket foldable regions.

It's also easy in vim (and probably emacs too) to create folds from syntax, which would work well with pretty-show's output.
