Hmm? Historically, in both XEmacs and GNU Emacs display tables were vectors. 
GNU moved to a fucked non-vector implementation that also gives t to
#'sequencep, and I want to move to a reasonably clean implementation that
uses char tables. Mike’s query should have cleared this up--it hadn’t
occurred to me previously that GNU would want people to pay attention to
(length (make-display-table)) in a non-Mule world, but that’s about as crazy
as things can get, I think.
