[vile] Is there any folding/hiding ability in [x]vile, or any add-on to do it?

[Chris Green]

As per the subject, is there any sort of 'folding' or 'hiding' ability
in vile or xvile?

I want to edit some files which need a few lines of 'code' at the top
and a line at the bottom that I would like to hide while editing so
that I can just see the 'business' content.
