There's also these two to worry about:
-- User Option: eval-expression-print-length
-- User Option: eval-expression-print-level
These are the values for `print-length' and `print-level' used by
`eval-expression', and thus, indirectly, by many interactive
evaluation commands (*note Evaluating Emacs-Lisp Expressions:
(emacs)Lisp Eval.).
by default, 12 and 4 resp.
In Tassilo's backtrace, I see ellipses at level 4, so I guess
eval-expression-print-level did that.
I also dug a bit deeper: if print_level is nil then backtrace sets the
maximum level to 8, so deeper calls will be elided. So try setting
print_level to some large number and see if that gets rid of the
ellipses. However, eight levels should be enough for just about
anything, no?
