[Mesa-dev] [PATCH 1/3] vbo: simplify vbo_save_NotifyBegin()

Brian Paul brianp at vmware.com

This function always returned GL_TRUE.  Just make it a void function.
Remove unreachable code following the call to vbo_save_NotifyBegin()
in save_Begin() in dlist.c

There were some stale comments that no longer applied since an earlier
code refactoring.

No Piglit regressions.
