bug#9463: 24.0.50; Errors should not be continuable

[Helmut Eller]

emacs -Q -eval '(let ((debug-on-error t)) (error "foo"))'

enters the debugger.  Pressing c somehow manages to continue.  That make
no sense to me.  The debugger should instead not continue and say
that errors are not continuable.
