Merge branch 'en/dirty-merge-fixes'

The recursive merge strategy did not properly ensure there was no
change between HEAD and the index before performing its operation,
which has been corrected.

  t6044: add more testcases with staged changes before a merge is invoked

  t6044: add a testcase for index matching head, when head doesn't match HEAD

  index_has_changes(): avoid assuming operating on the_index
  read-cache.c: move index_has_changes() from merge.c
