[armedbear-devel] [PATCH] Add SYS::*INVOKE-DEBUGGER-HOOK*

The first patch adds SYS::*INVOKE-DEBUGGER-HOOK* which is like *DEBUGGER-HOOK* but is observed by INVOKE-DEBUGGER even when BREAK is called. This obliterates the need to redefine SYS::BREAK in swank-abcl.lisp. A patch for swank-abcl is also attached. -T.
