Unfortunately, (R) and (W) are valid markups for enumerated
lists, as described at:
https://docutils.sourceforge.io/docs/ref/rst/restructuredtext.html#enumerated-lists
So, we ned to replace them by:
(R) -> (Read)
(W) -> (Write)
As otherwise, (R) will be displayed as R., with is not what
it is desired.
There's no need to touch (RO) and (RW).
