Dag H. Wanvik commented on DERBY-4387:
--------------------------------------
Bryan, I think the indentation is correct; but my new lines use blanks rather
than tabs, I have given up
on tabs entirely lately. (I used to try to keep tabs-only files that way, but
there are very few of them left, most already have many changed lines with
space indentation.)
