[xml] Adjacent text node merging

[Nikolay Sivov <bunglehead gmail com>]

I think it's more a question for Daniel, but any help is welcome of 
course. Libxml2 merges text nodes to a single node when you add text 
child next to existing text node for example, so at least 
xmlAddNextSibling, xmlAddPrevSibling and xmlAddChild are doing that. For 
a project I'm using libxml2 I want all nodes to be preserved as I add 
them, so for example I can edit text content of particular text node in 
children list. The question is what could or will potentially break if 
I'll use my own versions of these tree manipulation calls that do not 
perform such merging? e.g. does a lib really expect to have only one 
text node with no text siblings somewhere in the code, or maybe libxslt 
does?

P.S. attached patch is just to fix a compiler warning I'm seeing with 
current git builds, obviously completely unrelated to this topic.
