Crash bug in CVS rsync's --cvs-exclude option

[Wayne Davison]

The --cvs-exclude option is broken in the CVS version of rsync because
of a cut-and-paste-induced bug in exclude.c:

        if (local_exclude_list) {
                for (n=0; local_exclude_list[n]; n++) {

+                        ent = local_exclude_list[n];
                        if (check_one_exclude(name, ent, st)) {
                                 report_exclude_result(name, ent, st);
                                return !ent->include;

This bug could cause the sending rsync to crash when it dereferenced a
NULL pointer.
