It turns out that I stumbled on this quite by accident...
I originally thought that the following was enough to setup
Debian elisp addons on an unpackaged emacs21:
(add-to-list 'load-path "/usr/share/emacs/site-lisp/")
It turns out that I needed to defconst debian-emacs-flavor first.
Without it, `(debian-startup 'emacs)` would run but exit early
without actually setting stuff up. So I ran it by hand, e.g. :
M-: (debian-startup 'emacs)
And _this_ lead to the error on load-file because of an emacs21
(mis-)feature (from NEWS):
*** The commands to evaluate Lisp expressions, such as C-M-x in Lisp
modes, C-j in Lisp Interaction mode, and M-:, now bind the variables
print-level, print-length, and debug-on-error based on the new
customizable variables eval-expression-print-level,
eval-expression-print-length, and eval-expression-debug-on-error.
So debug-on-error evaluates to `t even when it's unset.
Any timeline for an emacs21 package? (We certainly need it by
the time woody freezes).
