[CMake] Subversion_WC_INFO and git svn

[Arnaud Gelas]

David,

you're right Suversion_WC_INFO should only focus on svn working copy!  
Such kind of features should be included in a specific module (git-svn  
one for instance).

I have just checked the documentation of git svn info which returns a  
lot of important information, but does not support yet git svn info -- 
revision... So, I guess we should wait for this one...

Now regarding Subersion_WC_INFO, could it be modified in such a way  
that if first check of a svn working copy, send a message status if  
not and return a default value ?

Just want to make sure, this could be an "expected" behavior...
