[DGD] Error handling, possible bug

[Raymond Jennings]

Hey um...is it normal for atomic_error to be bypassed if an error
within atomic context is caught?

I was playing around with the "return a string from an error handler"
feature and noticed that atomic_error got skipped if the error in
question happens to be caught.

Also, is there supposed to be any functional difference between
catch(expression) and catch{statements}:{morestatement} in terms of
calls to driver->foobar_error(...)?
