---------------------------------
Attachment: derby-4087-statistics.stat
derby-4087-statistics.diff
Uploading aother patch for this issue, which re-introduces the changes that had
to be rolled back.
derby-4087-statistics fixes the formatting errors seen by Knut and Bryan. Since
I could not
use java.util.regexp, I hand-coded three patterns in StringUtil.java this time
around.
The reason for all this text massaging is that the qualifiers are pre-formatted
before the output indentation level is knows, which leads to the weird
formatting seen. The new method
StringUtil.ensureIndent fixes that problem.

> Currently, the printing is often inconsistent:
> - some subtrees not printed
> - wrong indentation due to missing newlines, or lacking level increments
> - redundant printing of subtrees (AST is really a DAG, would be nice to print
> only once and then refer back to show aliasing)
> - some items printed twice due to inconsistent usage of pattern
