$ cat t.c
/// \brief A function.
/// \param X an argument
/// \param Y an argument
int foo(int X);

$ clang -fsyntax-only -Wdocumentation t.c
t.c:3:12: warning: parameter 'Y' not found in the function declaration
[-Wdocumentation]
/// \param Y an argument
           ^
t.c:3:12: note: did you mean 'X'?
/// \param Y an argument
           ^
           X
1 warning generated.


We should not be suggesting 'X' as a FixIt, since it is already covered by
another \param.
