See the tracker bug. case ${REPLACING_VERSIONS} in 1.1.[45]|1.1.5-r[123]) Doesn't account for multiple values in RV!
The test is for a single version being replaced and matching a certain string, which formally is a valid condition. I'm not going to spend any effort to catch the pathological case of more than two versions being replaced for an unslotted package, when the only effect is to print an elog message. Anyway, the last version matching the test was removed three years ago, so I believe we can consider this obsolete.
