[jdom-interest] getChildTextNormalize()

[Alex Rosen]

JDOM used to work this way, and after *quite* a bit of discussion, we
changed it. There are many of APIs that return null to indicate that the
item doesn't exist (that is the meaning of null, after all). E.g. the Map
interface in Java collections. The discussion was in June and July 2000
(wow, that was a long time ago...) if you want to take a look.
