After these discussions, I think this rule change was not a good idea. 
It effectively enforces these kinds of inconsistencies.  For example, if 
you ever refactored

     "DateStyle is wrong"

to

     "%s is wrong"

you'd need to adjust the quotes, and thus user-visible behavior, for 
entirely internal reasons.  This is not good.  And then came the idea to 
determine the quoting dynamically, which I think everyone agreed was too 
much.  So I don't see a way to make this work well.
