  * harness: remove a dirty hack from patch tree generators
  
  This re-adds a slightly modified version of sizeTree which we use to
  calculate the number of pairs in a flattened Tree.

  * harness: treat empty hunks specially in checkPatch
  
  See the comment in the code. I wonder why this hasn't come up earlier.

patch b0a689417ade345d2f7b60e7d8969439a96d5710

  * harness: remove code we no longer need

patch 5f2996bf7f298c8445740f9fe847fc046dbfd17c
Author: Ben Franksen <ben.franksen at online.de>
Date:   Sun Jul  7 10:00:08 CEST 2019
  * harness: never generate empty hunks

patch 08d6977bb518bca5024ecad7e87fc6fd29055d79

  * improved test case generator for RepoPatches
  
  We previously generated RepoPatches by merging prims from a Tree. While this
  generates conflictors, it never generates sequences where a patch depends on
  a conflictor. The new generator (which can only be used for patch types that
  have a Merge instance i.e. not prims) directly generates an RL of patches,
  making sure we cover all possible cases.

patch 39f81cf1b5ebc727677b74fe97e20578af520f2f
Author: Ben Franksen <ben.franksen at online.de>

  * harness: limit number of flattenings in propConsistentTreeFlattenings
  
  The number of flattenings grows exponentially in the worst case, so this
  helps to keep the test reasonably efficient even if we crank up the number
  of QC tests.
