I think this can be implemented in a simpler and more powerful
way. Just adding a boolean member to filestruct would allow us to
have such functionality. I also think my suggested approach has
some advantages and make implementation of other features simpler:
  - once the line is removed, the anchor is also removed;

  - if lines are added before/after the anchor, the anchor is
  automagically moved;

  - multiple anchors could be set on the same buffer;

  - cycling through anchors or "go to next/previous anchor" would
  be easy to implement.

If you wish, I can come up with proof-of-concept of such a feature.
