This patch adds a goto control similar to the search control currently available. The goto control permits the user to specify a line number to jump to. When in blame, Control-G is bound to display this control. Signed-off-by: David Fries <David@Fries.net> Signed-off-by: Pat Thoyts <patthoyts@users.sourceforge.net>
