Playing a bit with xmlKeepBlanksDefault(), xmlSaveFile and xmlSaveFormatFile 
it appeared that my previous observations were partly wrong.

xmlKeepBlanksDefault(0) is _not_ the default, and not what we want as a 
default : it drops and add whitespaces. But I think this option should be 
accessible to the user in a way or another.
So I'm thinking again of adding a per-parser and per-document option, as well 
as a global one, to keep or not blanks.
On the other hand I don't know how this will behave in a multi-threaded 
environnement. So only let the global parameter would be safer. I'll try 
making tests about this.

Anyway we need to remove the calls to xmlKeepBlanksDefault() we actually do.


Cheers
