These folding arrows are based on the English Wikipedia setup, created
by Edokter. I don't see why all wikis can't benefit from them.
The only complication is with right-to-left languages, where ◄ is needed
instead of ►. I have updated the i18n file in a way that I hope is
sufficient.
When JavaScript is disabled, the fallback is a bit unintuitive, but no
worse than what is already there.
