 * ```soql
 * SELECT id| FROM x    : Cursor touching the previous identifier token:
 *                        we want to continue completing that prior token position
 * SELECT id |FROM x    : Cursor NOT touching the previous identifier token:
 *                        we want to complete what comes on this new position
 * SELECT id   | FROM x : Cursor within whitespace block: we want to complete what
 *                        comes after the whitespace (we must return a non-WS token index)
 * ```
