[R. Matthew Emerson]

You want to take this bug, Shannon?  Or is format.lisp too horrible to contemplate?

This line of code is especially egregious because if ASDF encounters an error when it’s loading files and the user tries to restart in the CCL IDE, the “Missing Argument” error throws to the AltConsole and recovery is basically impossible, because the error happens in the drawing of the restarts GUI window.

I have been working around this by modifying compatfmt to get rid of the pretty-printer gobbledygook on CCL (that’s what compatfmt is for, after all), but if this is really a bug in CCL’s implementation we should probably fix it there.
