Question

If I write the following code in vim at the moment

const SomeType & some_function (<ENTER>

then vim will continue the next line at an indent of two tabs. I want it to indent the next line with only one tab.

I know cindent exists, but I can’t work out what syntax will make this happen.

(N    When in unclosed parentheses, indent N characters from the line
      with the unclosed parentheses.  Add a 'shiftwidth' for every
      unclosed parentheses.  When N is 0 or the unclosed parentheses
      is the first non-white character in its line, line up with the
      next non-white character after the unclosed parentheses.
      (default 'shiftwidth' * 2).
