While discussing the new gets_s.c in D12785, ed@ suggested putting

{}'s around the if (c == EOF) block to prevent potential 'trailing else'
issues from being introduced when refactoring. As my gets_s() code
is based on this, it makes sense to fix the same issue here first
here and now, then do an svn copy again to capture this history).
