Hi,
I've been using slime and the autodoc feature fails to execute for fun's having #% char in the name. That's due to elisp's format string.
I'm attaching the slime.el diff. Actually this patch is nothing more than a hack, i've catched the error condition and made it work until somebody pushes a real fix.
evrim.
