Yes, the main issue was introduced 2 years ago when replacing a dotted
optional arguments list with an #:optional keyword and not adapting a delegate
procedure. :-(

This shameful bug should be fixed by commits
f71b0b8310e6b297866147a11e3fd0dd5db13beb and
fad58ca8c221def75093463e917f66fc006f3df5.

IMO This bug definitely requires a bug-fix release.  I will continue my
automatic testing endeavor for a bit before releasing 1.1.1.

Thanks for the bug report.
