Ah, separate binding, indeed. In *inferior-lisp* buffer *debugger-hook*
variable is NIL and in Slime-REPL buffer it's swank's debugger function.

OK, thanks. I ended up redefining swank:swank-debugger-hook function in
~/.swank.lisp file. It's a bit ugly but does what I want.

My "debugger" just prints the condition type, available restarts and
error message. Then it invokes ABORT restart automatically. I don't need
Slime's debugger because SBCL does not give much useful information
there anyway (even with the highest debugging level).
