with-demoted-errors use of condition-case-unless-debug is annoying.
If I want to debug a condition-case, I'll set debug-on-signal non-nil.
As it stands, with-demoted-errors is not useful if you want to write an
ERT test (for reasons I haven't investigated).

(defun foo ()
  (with-demoted-errors (error "error!"))
  t)

(ert-deftest test-foo ()
  "Test foo"
  (should (foo)))

M-x ert RET test-foo RET

Selector: test-foo
Passed: 0
Failed: 1 (1 unexpected)
Total:  1/1

If you replace with-demoted-errors with ignore-errors, the test passes.
