} Is it a case of the two requiring different handling?

Possibly, but the patch testing for -2 doesn't change anything.

If I change it to test showinglist == -1, then the case in this thread
works but TRAPINT handlers break it again (the original problem from the
thread ending with 38048).

So I begin to suspect that testing only showinglist isn't sufficient, but
I'm not sure what else to look at.
