/* Takes an expression to test for SUCCESS and a message, which
may include printf-style arguments.Logs the message, then
tests the expression.If it is zero, indicating failure,
emits the message as a failure.

Somewhat tricky to use:

– SUCCESS must not have side effects that affect the
message, because that will cause the original message and
the failure message to differ.

– The message must not have side effects of its own, because
it will be printed twice on failure, or zero times on
success if quiet is set. */
