Since writing the above, I realized that the following is a realistic 
scenario. 2.6 or 2.7 code a) uses has/set/getattr, so unicode literals 
would require a change; b) uses non-ascii chars in unicode literals; c) 
uses (or could be converted to use) print as a function; and d) 
otherwise uses a common 2-3 subset. Such would only need the u prefix 
addition to run under both Pythons. This works the other way, of course, 
for backporting code. So I am replacing 'most' with 'some unknown-to-me 
fraction' ;-).
