The original bug report is about the ‘message’ function, not about 
formats in general. For that function, "%s" is the longstanding way to 
output arbitrary strings. For formats in general, one can use the 
‘format’ function (which does not translate quotes) or the 
‘format-message’ function (which does); this suffices in practice.

As a practical matter Emacs messages often have contractions and I am 
not aware of a GNU style guideline that would discourage their use. 
Plus, some uses of apostrophes in messages are for possessives, not 
contractions. Surely we should not ban contractions and possessives 
merely because our API has glitches with apostrophes.
