[PATCH] svn-graph.pl in tools/client-side broken

Subversion 1.2.0 introduced a change in the svn_ra_get_log api, but
svn-graph.pl wasn't updated.
The exact error message is :

$ ./svn-graph.pl
digraph tree {
Usage:
svn_ra_get_log(session,paths,start,end,limit,discover_changed_paths,strict_node_history,receiver,receiver_baton,pool)
$

The fix is to add the limit argument to the function call.
