I would like the text widget command edit undo to return 
as a result the range(s) of characters in the widget that 
were modified (impacted) by the undo operation.

This would allow to apply special processing to these 
ranges, e.g. colorize these chars, flash them, and so on.

Same request for redo, of course.

TIP #449 voted as accepted --> implementation merged to trunk (8.7) only.

Proposed fix : [6cd8c5d9] (implementation only, no documentation update nor tests so far, but wilco)

I think this needs a TIP (and I have submitted it to the TIP editor).

There is a mention of this in the comments of TextUndoRedoCallback (in tkText.c).
