Aren't folds supposed to do this? I.e., record all the output but only show it to the user if the command exited non-zero.

According to:

  https://blog.travis-ci.com/2013-05-22-improving-build-visibility-log-folds

they auto-fold individual commands _except_ the ones in the script section. Is there a way to manually mark folds in the output?

Hmph. I could not find an answer from travis, but googling seems to turn up that something like this would work:

I've queued a CI job to see if this actually works. :)
