Yes,I said that,
...but that is not what happened.
I was totally wrong. I misinterpreted the unwind error
messages as continuing code (because of the accidental
match in line number inside the function to the line number
of my prompt!
CONCLUSION:
error() without the \n prints out more information
error() with the \n only prints out the line inside.
seems odd, since I put the line there I know where it came
from.
Oh well.
sorry for the confusion. It looks like all is well with
the function.
