Myrna van Lunteren updated DERBY-2794:
--------------------------------------

    Attachment: ref-single.html
                rreftrimfunc.html
                DERBY-2794.diff

I'm attaching a patch that adds the contents of the doc,.I expanded some of the 
details so I could understand the syntax.

I have not tested the examples.

Also, I have a question: what does the first sentence of the explanation mean: '
If the trim specification { LEADING | TRAILING | BOTH } is not specified, it 
defaults to false.

What is it that defaults to false?

> Document ansi trim functionality
