I have a new repro of an ITS#8264 and ITS#8299-like situation, but with different input data.

The referenced test runs twice: once with mdb_cursor_del and once with mdb_del.

Just like before, mdb_cursor_del performs correctly whereas mdb_del corrupts the database. In this case, mdb_del incorrectly removes one extra key (a key prefixed with 03000000000000003a...).

Thanks. Fixed in git. This appears to have been broken by commit d9423e13f85bac7c33083a4b872c022d18a41232

On a related note, I have switched to mdb_cursor_del whenever possible, but there are a couple of situations where clients of my library only have the key during a scan and so must use mdb_del instead of mdb_cursor_del. Just letting you know that I took your advice from earlier, but must still use mdb_del here and there.
