    In zwei in Release 5.0 [GC'd Beta Test rev 2], on Lisp Machine Janis Joplin (3600):

    I did M-X set package and typed "foo" to the prompt What Package?.  It
    accepted the name as a lowercase string and created the package "foo".
    It should have created a package named "FOO".

Fixed in the source (ZWEI:READ-PACKAGE-FROM-MINI-BUFFER).  Should this be patched?
