SyncSort Sort is Not Stable

Original post is here eklausmeier.goip.de/blog/2013/08-15-syncsort-sort-is-not-stable.

A colleague of mine noticed some strange behaviours in his programs. It was later discovered that this is due to SyncSort not conducting a stable sort. Stable sort means that the sequence of elements in input is not changed if there is no strict need to change them.

Unfortunately, the documentation of SyncSort apparently does not contain a hint on that.
