If we wanted to have that behavior by default, then rather than change
lots of code gradually, how about making a new global flag
`debug-on-caught-error' which, when t, would make errors invoke
the debugger when they are about to be caught?
If `debug-on-caught-error' is `debug-on-error', then the value of
`debug-on-error' would control the behavior of errors about to be
caught.
