 # BSD, macOS and others support colors with ls -G.
 # GNU ls and FreeBSD ls takes --color=auto. Order of this test is important because ls also takes -G but it has a different meaning.
 # Solaris 11's ls command takes a --color flag.
-# Also test a no-op -- because we'll want to define this function even with an ls that can't do colors (like NetBSD).
+# Also test -F because we'll want to define this function even with an ls that can't do colors (like NetBSD).
