Merge #15659: [docs] fix findFork comment
c968780785 [docs] fix comment: the return value of findFork is _not_ an ancestor when the specified block is on the active chain (r8921039) Pull request description: The return value of findFork is an ancestor of the specified block only when specified block is _not_ on the active chain. When it is on the active chain, the return value is the specified block itself, not an ancestor of it. ACKs for commit c96878: promag: utACK c968780, however comment could be shorter. ryanofsky: utACK c968780785c18bd6d0a8659c9e251ccf8fdc91dc. Only change since last review is squash Tree-SHA512: bb05d734059898784c4a59b5b0344719eb4dfb2d49a0f7f705fcb2eb630702e66be81c01299185faf0c219fa9f9aa64cbdf6d5f91e0b3dce0ff420909a454a18
