Silence warning by Apple Clang 4.2 about adding an integer to a string

It gives a good suggestion on what to do and even shows us how to do
it.

doc.cpp:2681:34: error: adding 'int' to a string does not append to the string [-Werror,-Wstring-plus-int]
            result += "        " + (column % tabSize);
                      ~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~
doc.cpp:2681:34: note: use array indexing to silence this warning
            result += "        " + (column % tabSize);
                                 ^
                      &          [                   ]
