[PATCH 0/5] activate diff.renames by default

[Matthieu Moy <Matthieu.Moy@imag.fr>]

I have always wondered why diff.renames was not activated by default.
I've had it to true in my configuration for 9 years, and I've been
teaching newbies to set it for a while without issue. I think it's
time to activate it by default, but please let me know if I missed a
reason to keep it to false.

In any case, the first 3 patches are useful cleanups.

Matthieu Moy (5):
  Documentation/diff-config: fix description of diff.renames
  t4001-diff-rename: wrap file creations in a test
  t: add tests for diff.renames (true/false/unset)
  log: introduce init_log_defaults()
  diff: activate diff.renames by default
