Subject: [PATCH] Problem: some standard copy paste formats do not work

Solution: add solution for copying text from Roam. This formats looks
like:
    - parent
        - child 1
        - child 2

The first line starts with a dash and space. The other lines also start
with spaces (multiple of 4 or 0), dash, space. Every 4 spaces is 1
indent in our format.
