Yes, it was t (the default). I actually had read about it on the EBDB
manual, but, since Emacs was asking whether to save, I interpreted that
variable as whether Emacs would ask at all. That is, I thought that if
the variable was t then Emacs would ask whether to save, and if it was
nil then Emacs would exit without saving and without any question.

The current behavior is a bit counter-intuitive. Not only for the
reason I provided above, but because, when I answer the question
positively (that I do want to save the buffer), Emacs asks for a file to
save the *EBDB* buffer. It then saves _that_ buffer (with its human
readable contents) to the just-specified file, and also appears to save
the actual database to its file, even though for my test I had
previously set `ebdb-save-on-exit' to nil. Apparently, answering
positively the buffer-offer-save question causes two saves.
Counter-intuitive. And what if the user is confused -- thinking that
Emacs was asking whether to save the _actual database_ -- and then
provides the path of the database file? Would not EBDB then save the
*EBDB* buffer there, overwriting the actual database, causing data loss?
Isn't it peculiar to EBDB that Emacs offers to save the
computer-generated contents of the *EBDB* buffer on exit? IIRC, when I
exit Emacs it does not offer to save my Org Agenda (only the actual Org
files from which it generated the agenda), nor Dired buffers, nor any
other computer-generated buffer.
