CmdContext::value_cell_key answers the cursor through project::cell_id, the
question the browser is given: only a Record is written, a records position
resolves to its real record, and a fold, an aggregate, a formula-owned cell,
a coordinate or creating column and a drill are each declined out loud.
clear-cell and paste take that door; commit and drill take the fold-only one.
