[PATCH v5 0/4] Detection of directory renames

Evolutions from v4 to v5:

(Jonathan Nieder) use memcpy, not strncpy overkill (Jonathan Nieder) split 2 funcs out of diffcore_bulk_renames (Jonathan Nieder) more comments (Jonathan Nieder) avoid allocating often-useless filespec too early (Jonathan Nieder) split into new func (Ævar Arnfjörð Bjarmason) convert C99 comments intended to stay to C89 ones

(Jonathan Nieder, Ævar Arnfjörð Bjarmason) reworked style of test script
(Jonathan Nieder, Sverre Rabbelier) use compare_diff_raw, not compare_diff_patch;
	anonymize hashes and scores
(Jonathan Nieder) use "git commit" in test instead of only plumbing, and use test_tick

listed a number of additional FIXME's
changed wording "factorization" -> "bulk move"
changed --detect-dir-renames to --detect-bulk-moves and
	--hide-dir-rename-details to --hide-bulk-move-details
first attempt at showing the "/*" suffix in bulk moves, for comment
stop maintaining testcases for --hide-bulk-move-details, I'm just keeping
	the patch adding the flag in sync with other code changes anyway.

Yann Dirson (4):
  Introduce bulk-move detection in diffcore.
  Add testcases for the --detect-bulk-moves diffcore flag.
  [RFC] Only show bulkmoves in output.
  [RFC] Allow hiding renames of individual files involved in a
    directory rename.
