Arg.  Minor enlightenment always comes after publication.

For some reason, the "fix" was actually changing the repl out of the 
:cl-user package (where my code currently lives) and into any other 
package.  Somehow that changes Slime's behavior.

If you think this looks like a Slime bug, I'll try to send them a bug 
report later this week.  Right now, I have a workaround, and there's some 
real code I want to write in my remaining time for today.
