 Cast NULL to (char *) in vararg calls to svn_dirent_join_many

 Why? On which platform do you expect a char* to have a different size
 and/or representation than a void*?

Alan, Brane specifically asked about practice not theory.

I was trying to point out that the "On which platform ..." 
question appeared to be based on the incorrect assumption that 
NULL macro would always expand to a void*.  Asking about the 
relationship between char* and void* is the wrong question.
