Ah, I don't use lexical binding in my package.  I probably should;
thanks for this advice!

Rather not applicable to my situation.  But out of curiosity: what are
"nested minibuffers" and where can I read about them?  In my Emacs, when
I try to issue a command which needs minibuffer while I'm in
a minibuffer, I get the message "Command attempted to use minibuffer
while in minibuffer".
