/**
 * An EBMessage associated with an EditPane that is sent just before its caret 
 * position changes in a "major way" to another location in the same Buffer.
 * These messages are tracked by the Navigator plugin, 
 * and other interested plugins.
 * 
 * jEdit plugins such as SideKick, Tags, Jump, CscopeFinder, etc, should 
 * emit this message whenever the user wants to jump from one position
 * to another in the same buffer.
 * 
 * For jumps to a different buffer entirely, it is not necessary for plugins
 * to send any message, since BufferChanging is sent by jEdit whenever 
 * EditPane.setBuffer() is called, and it serves as a PositionChanging message
 * also.
