When stepping, the (search-forward "\n  debug(") in
debugger-setup-buffer sometimes fails.  To reproduce this 

1. eval this

  (progn
   (defun foo ()
     (debug nil 1)
     (debug nil 2))
   (setq toggle-debug-on-error t)
   (foo))

2. The debugger pops up with the message:
   Debugger entered: (1)
     foo()

3. At the line with foo(), press d (i.e. debugger-step-through).

4. Now the buffer starts with:
   Debugger entered--beginning evaluation of function call form:
   * (debug nil 2)

5. Now press c (i.e. debugger-continue) on the line with the *.

6. The debugger enters recursively with the error:
   Debugger entered--Lisp error: (search-failed "\n debug(")
