    *ZMACS-BUFFER-LIST* and *ZMACS-BUFFER-HISTORY* are almost redundant, 
    . . .                           thus making it almost seem like there is only
    one variable rather than two.

Exactly.
    
    Agre's bug report is that c-m-L with an argument doesn't always do what you
    would expect from the List Buffers listing, because buffers created by
    ZWEI:LOAD-FILE-INTO-ZMACS don't work.
    
Right.

    It might be better to get rid of *ZMACS-BUFFER-HISTORY* and just keep
    *ZMACS-BUFFER-LIST* sorted in order of recency of selection.  However this would
    cause c-- c-m-L to tend to bring back an "obsolete" dired or mail buffer.
    There could be a flag in a buffer which makes it invisible to ROTATE-BUFFER-HISTORY.

Hear hear.  There could also be a ZWEI:LOAD-FILE-INTO-ZMACS argument
(defaulting to whatever) giving the initial setting of this flag.
