What is the advantage of this peculiar formatting?

I saw this format used for comma-separated lists in some C ++ code (although this can apply to any language):

void function(  int a
              , int b
              , int c
             )

I was wondering why someone would use this in a more common format, for example:

void function (int a,
               int b,
               int c
              )

This is a fairly common coding style when writing SQL statements:

SELECT field1
     , field2
     , field3
--   , field4
     , field5
FROM tablename

Benefits:

  • Allows you to easily add, remove or reorder fields without worrying about this trailing final comma.
  • Allows you to easily comment out a string (TSQL uses a "-") without violating the rest of the statement.
