CGrammar improvements:

Browse Source 
- periods after "Call the function" and "Result of the function"
  - conditional operator in assignment expression now says "otherwise the value"
  - struct members now use "`identifer` as type" in declarations
  - fix chained designated initializers, e.g. s.i[0] = x and [0][0] = x
  - fix post/pre-incremented/decremented array elements
  - correct positioning of "is nonzero" in multidimensional array locations
