Of course not. :-)
By the way, what does Isearch do with such org-mode folded buffer? Does
it unfold the content, ever?

I don't agree this is a good idea. At the moment, all these tests are
in the same not too big defun that sets them. This kind of keeps things
together - for instance if a new test was to be introduced, only this
one function would need amending.

I'm pretty much ready to do this. But maybe you could answer my
question about unfolding org-mode buffers above, first. Thanks!
