[xml] default entities

[Guilherme Balestieri Bedin <guilherme tteng com br>]

Hi,

 I did a small change in xmlEscapeEntities() from  xmlsave.c to take 
account of the xmlSubstituteEntitiesDefaultValue parameter.
So, now I can control if default entities will be substitute or not by 
xmlSubstituteEntitiesDefault() in tree serialization like with the parser.

I wanna now if this behavior can be added to libxml2 ? If yes, how is 
the process ?
Bellow is a diff from my xmlsave.c against the libxml2-2.6.23 xmlsave.c.

cheers,
