Subject: Org reader: undo code duplication

Some code was duplicated (copy-pasted) or placed in an inappropriate
module during the modularization refactoring.  Those functions are moved
into a `Shared` module, as was originally intended but forgotten.
Better documentation of the respective functions is a positive
side-effect.
