Log folds which are open by default

It would be useful to have a way of displaying warnings within a folded section and so have the fold open by default - so you see the warning but can then collapse the section. I was thinking of an extra parameter to travis_fold:end perhaps which just set the fold to be open by default?

I’ve worked around it by closing the fold and then creating another one, but it makes for (even) messier shell scripts. Example output in this log. If the warning weren’t displayed, there would be no continue.ci fold - just prepare.ci spanning lines 451-811.
