The function used to write to file is xmlSaveFormatFile or 
xmlSaveFormatFileEnc depending on the given encoding parameter.
The 'format' parameter is set to 1. 

Reading libxml2 doc for xmlSaveFormatFile:
"Note that format = 1 provide node indenting only if xmlIndentTreeOutput = 1 
or xmlKeepBlanksDefault(0) was called"

consider this other extract from the doc :
#define     xmlIndentTreeOutput
 Global setting, asking the serializer to indent the output tree by default 
Enabled by default

So the only thing we need is to call xmlKeepBlanksDefault(0), which is done in 
the parse_xx methods.
The consequence is that, theoraticaly, the output will be formatted only if 
something has been parsed before (I did not test this behavior).

I think that the most simple thing to do is to call xmlKeepBlanksDefault(0) in 
write_to functions.
On the other hand we'll have it called more than necessary. So we could call 
it in Document::Init::Init() and remove it everywere else.

If you agree with that I'll commit a patch soon.
