21  '''This plugin ensures that when a newline is entered, it 
22  has the same amount of whitespace as the previous line. This 
23  is a fake form of auto-indent, but it doesn't know about adding 
24  indentation when the next line should be indented another level. 
25   
26  Unless otherwise bound, Shift+Enter will ignore this effect.
