I had a brief look at the codemirror code and manual, and I see two
potentially useful things:
- doc.markText(from: {line, ch}, to: {line, ch}, ?options: object) → TextMarker
  which has a 'collapsed' property.
  From how I understand it, one should be able to create a marker
between two lines and collapse it.
  http://codemirror.net/doc/manual.html#api_marker

- the codefold add-on (http://codemirror.net/doc/manual.html#addon_foldcode)
  although this may be less suitable in this case.

Is this more or less what you had in mind?

How to find out which lines are suitable for collapsing, from mergely?
And how/where should one start hooking this into mergely?

Thanks,
Thomas
