[jdom-interest] patch for skipLeadingWhite

[Bradley S. Huffman]

Aaaa, you don't want to do that. skipLeadingWhite is used to find the 
first non-white node beginning with the node starting at index "start",
which may not be the first content node.

Which serialization tests are failing? The ones in jdom-test as of 4/16
all pass.
