change in /usr/bin/bc with CTRL-d no longer exit

On 14.1 and prior, a CTRL-d will exit a bc session.

Today I noticed that on 3 different 15-CURRENT systems, it appears to be 
ignored.  Works fine otherwise and I can exit the bc session with the 
'quit' command okay.

I re-tested this on the system console on fresh login just to rule out any 
terminal madness.

Here's a paste of what I see:

I did a fresh install of 14.1 and it works as it did previously.

No biggie, just wondering if anyone else on -CURRENT can confirm/deny this 
change on their system.
