148 heluecht 2018-06-19: from my point of view this whole code part is useless.
149 It just renders the body message of technical posts (Like, dislike, ...).
150 But: The body isn't visible at all. So we do this stuff just because we can.
151 Even if these messages were visible, this would only mean that something went wrong.
152 During the further steps of the database restructuring I would like to address this issue.

1377 * Selectively flattens a tree-like item structure to prevent threading stairs
1379 * This recursive function takes the item tree structure created by conv_sort() and
1380 * flatten the extraneous depth levels when people reply sequentially, removing the
1381 * stairs effect in threaded conversations limiting the available content width.
1383 * The basic principle is the following: if a post item has only one reply and is
1384 * the last reply of its parent, then the reply is moved to the parent.
1386 * This process is rendered somewhat more complicated because items can be either
1387 * replies or likes, and these don't factor at all in the reply count/last reply.
1389 * @param array $parent A tree-like array of items
