Probably by accident. My natural instinct is to think that nobody
permits the use of EXPN any more, so it is not in my consciousness.

Thanks for pointing out this anomaly. I'll check them all out in the
current source code, and fix the problem, as it seems reasonable that
EXPN should show the error. Unless I find some buried comment in the
code which explains why a change was made. If so, I'll document it.

This may or may not happen before the 4.50 release, as I'm about to be
away.
