Indentation of ?: in C-mode (was: scratch/fontify-open-string. [Was: CC Mode and electric-pair "problem".])

This is one of those rare cases where sm-c-mode handles it better:

    find_start_value
      = CONSP (state.levelstarts) ? XINT (XCAR (state.levelstarts))
        : state.thislevelstart >= 0 ? state.thislevelstart
        : find_start_value;

This said, I don't see either indentation as problematic and I'm not
sure what would be "better for readability".
