Pressing Ctrl-C where?  Emacs redefines SIGINT so that it is produced
by C-g, not by C-c (because the latter is used in many key sequences),
so I presume you don't mean typing Ctrl-C into the Emacs window.  But
then where did you type it?

Also, by "starting emacs at a xterm prompt", do you mean "emacs -nw"
or do you mean a GUI session started at the shell prompt?

You mean, call 'pp' in a kill-emacs-hook and _then_ deliver a SIGINT?
Or do you mean that having `pp' called from kill-emacs-hook will cause
the abort even if Emacs is shut down normally, via "C-c C-c"?

What are those prj-* functions?
