Commit Message

Aleksei Vetrov via Libabigail Jan. 1, 2020, midnight UTC
  Leaf changes (as reported with --leaf-changes-only) to variables were
miscounted as changes to functions.

	* src/abg-comparison.cc
	(apply_filters_and_compute_diff_stats):	Increment the correct
	counter for leaf variable changes.
	* tests/data/Makefile.am: Add new test case files.
	* tests/data/test-abidiff-exit/test-leaf0-report.txt: New test
	case.
	* tests/data/test-abidiff-exit/test-leaf0-v0.cc: Ditto.
	* tests/data/test-abidiff-exit/test-leaf0-v0.o: Ditto.
	* tests/data/test-abidiff-exit/test-leaf0-v1.cc: Ditto.
	* tests/data/test-abidiff-exit/test-leaf0-v1.o: Ditto.
	* tests/test-abidiff-exit.cc: Run new test case.
