+The 'cinoptions' option sets how Vim performs indentation. The value after
+the option character can be one of these (N is any number):

+In the list below,
"N" represents a number of your choice (the number can be negative). When
there is an 's' after the number, Vim multiplies the number by 'shiftwidth':
"1s" is 'shiftwidth', "2s" is two times 'shiftwidth', etc. You can use a
