+# NEEDSWORK: The 'diff --check' test is left as 'test_expect_failure' due
+# to an underlying issue in oneway_diff() within diff-lib.c.
+# 'do_oneway_diff()' is not called as expected for paths that could match
+# inside of a sparse directory. Specifically, the 'ce_path_match()' function
+# fails to recognize files inside a sparse directory (e.g., when 'folder1/'
+# is a sparse directory, 'folder1/a' cannot be recognized). The goal is to
+# proceed with 'do_oneway_diff()' if the pathspec could match inside of a
+# sparse directory.
