Steps to reproduce:
* ABCL from svn, updated a few minutes ago.
* Slime from CVS.
* M-x slime-scratch
* Put (defun test (x) ,bar) in the buffer
* Press C-c C-c
You'll see "Evaluation aborted." in the minibuffer even though the
debugger should have popped up complaining about comma not being inside
C-c C-c is SWANK-COMPILE-STRING in swank-abcl.lisp.
If you follow the control flow, you'll see that in SLDB-LOOP (we come
here through *DEBUGGER-HOOK*) in swank.lisp,
__the UNWINDED-PROTECT's protected form is *never* executed and it goes
straight to the cleanup forms.__
