   Comments

   idn: clarify null-termination on Windows
   Add comments to clarify that a terminating null is always present in
   the buffers returned to the caller.
   
   The curl APIs `win32_idn_to_ascii()` or `win32_ascii_to_idn()` receive
   a null-terminated UTF-8 string as input. They first convert it to wide
   chars by first asking `MultiByteToWideChar()` to calculate the length,
   by passing -1. This API returns the length with the null char included
   (= `strlen() + 1`), does the conversion, with the output also
   null-terminated. `IdnTo*()` preserve this null character as documented.
   Then we pass this null-terminated, fixed-length buffer ito
   `WideCharToMultiByte()`, which keeps preserving the null, ending up in
   the buffer returned to the caller.
