mark {name} contains empty anchors

Error message

mark {name} contains empty anchors

What it means

Raised while resolving a vim Position::Mark when the mark exists as Mark::Local but its anchor list is empty. The mark was recorded without usable anchors (e.g. the buffer snapshot they pointed into is gone), so the position cannot be computed.

Solutions

1. Re-set the mark; its stored anchors were invalidated by buffer edits
2. Reopen the file/restart the session to clear stale mark state
3. Report the bug if empty anchors persist after re-setting the mark
