New Revision: 1850781
URL: http://svn.apache.org/viewvc?rev=1850781&view=rev
Log:
Extend the blame callback with a string length parameter.
* subversion/incluce/svn_client.h
* subversion/libsvn_client/blame.c
(svn_client_blame_receiver4_t): typedef for new callback
(svn_client_blame6): new API using the svn_client_blame_receiver4_t callback
* subversion/libsvn_client/deprecated.c
(svn_client_blame5): moved API there, calling svn_client_blame6 using a
callback shim
(blame_wrapper_receiver3): callback shim for svn_client_blame5
