This patch series includes 3 small code cleanups, 1 small bug fix (or
perhaps just a UI improvement -- it's a very minor issue either way), more
testcases, and 3 performance improvements. The first 7 patches are
relatively easy to review, while the second to last one...is a bit more
involved (but provided the biggest performance boost).

Changes since v2:

 * Fixed spelling error: remove unnecessary double c in 'unneccessary'
   (thanks to Christian for spotting)

Elijah Newren (9):
  diffcore-rename: rename num_create to num_destinations
  diffcore-rename: avoid usage of global in too_many_rename_candidates()
  diffcore-rename: simplify limit check
  diffcore-rename: reduce jumpiness in progress counters
  t4058: add more tests and documentation for duplicate tree entry
    handling
  t4058: explore duplicate tree entry handling in a bit more detail
  diffcore-rename: simplify and accelerate register_rename_src()
  diffcore-rename: accelerate rename_dst setup
  diffcore-rename: remove unnecessary duplicate entry checks
