Subject: 1.0.24.28: make unbind in the runtime zero the value of the binding
X-Git-Url: http://repo.macrolet.net/gitweb/?a=commitdiff_plain;ds=sidebyside;h=777ed58b46a76b4d260a1aede699117323105d2e;p=sbcl.git

1.0.24.28: make unbind in the runtime zero the value of the binding

... to parallel what the Lisp side does. As far as I see the rationale
for doing that (in doc/internals/specials.texinfo) does not apply here
since signals are blocked when the dynbind functions are called. That
said, instead of adding documentation let's fix it.
