It's possible to force Emacs to print a backtrace by binding `debug-on-error', however, that is incorrect because it changes the meaning of `with-demoted-errors' and `condition-case-unless-debug', causing code that would normally work to fail with an error. Instead, `signal' should print a backtrace if in batch mode and if it jumps to the top-level error handler. It looks like this logic could be special-cased in signal_or_quit, similar to the debugger logic.

It's possible to force Emacs to print a backtrace by binding `debug-on-error', however, that is incorrect because it changes the meaning of `with-demoted-errors' and `condition-case-unless-debug', causing code that would normally work to fail with an error. Instead, `signal' should print a backtrace if in batch mode and if it jumps to the top-level error handler. It looks like this logic could be special-cased in signal_or_quit, similar to the debugger logic.
