But it was later said that making the change fixed a different bug...
I probably misunderstood something?!?

Ah, yes.

IIUC, the rationale for Richard's original change was to allow a
program using pushnew to be evalled in non-compiled form without
loading cl (because it needs the _function_ adjoin defined there).

It doesn't help in the non-compiled case.
