Another bad argument, because we are talking about format strings, which
you cannot be replaced by "%s".

>>>           (error "Can't find `%s' in %s" thing where)))
>>>   =>      (error "Can%'t find %`%s%' in %s" thing where)))

A better way would be a new modifier to place quotes around the
argument.  That's what GCC is using now.  Also, contractions like don't
should be avoided anyway.
