[It was python, not Idle, that had a problem with the tab.]

The stdlib .py files (should all) use the PEP8 standard 4 space indents. 
  Idle comes configured to convert tabs to 4 spaces.

Notepad++ does not.  Settings -> Language Menu/Tab Settings lets one set 
a default tab handling setting and langauge-specific tab settings. 
Python should be configured for tabsize 4 and [X] replace tab with 
space.  Unless, of course, one uses tabs.  But then one should either 
not edit stdlib files or make sure to switch every time one edits one. 
I have had settings disappear after upgrading (ugh).

Similar comments apply to other code editors.
