+Subject: [PATCH] Remove broken agrep test entry
+
+It's meant to cause agrep to return with exit code 2, but asserts that it's
+exit code 1 instead.
+
+It's meant to ensure that using ".*" as pattern results in exit code 2 because
+it matches also an empty string. However, glob expansion results in ".*"
+picking up files such as "." and ".." from the CWD, which get interpreted as
+valid pattern. This results in exit status 1 (no match found) which is what
+the .ok file expects, but that's invalid.
+
+With bash 5.2, glob expansion no longer matches "." and ".." by default, so
+the test works as intended by accident, causing a mismatch with the expected
+wrong exit code.
+
+It's unfortunately not easily possible to avoid glob expansion in this case.
+
+Just remove the test for now.
