Comment:

 Merged to master (this got fast-forwarded because nothing else went into
 master after this branch was created, so there's no merge commit):

 {{{
 * 862b15f [2182] Simplify code further
 * 823c4a9 [2182] Simplify RBTree::deleteHelper() and also make it non-
 recursive
 }}}

 Resolving as fixed. Thank you for the review Michal.
