I've now mentioned this in the manual, but I've been trying to grep
through the code and see why/where this is done, and I'm coming up
empty.
Does anybody know? And is this a feature or a bug?
`eval-expression-debug-on-error' doesn't sound like something that
should affect `M-x debug', and the other `eval-expression-' variables
are not heeded by doing `M-x debug'. So it seems inconsistent and
somewhat confusing.
