New submission from anatoly techtonik <techtonik at gmail.com>:

Since 2.4 doctest converts all tabs to 8-space sequences in test source. 
It should do the same with output it receives for comparison. Right now 
there is no way to write a correct doctest if the output includes tab 
character. See attached doctabtest.py

This change would be backwards compatible, because all tests with tabs are 
either fail or run with doctest.NORMALIZE_WHITESPACE flag, which is 
usually inappropriate for doctest cases that involve tab formatting.
