indentation of structures/enums

[Alfred M. Szmidt]

Hi,

can't find anything in the GCS about how to "properly" indent structs
and enums, and all the code I've seen is abit ad-hoc when it comes to
how to indent them.  Personally, I have no preference, would be nice
to have a recommended variant though.

For enum's I've see the following,

enum
{
  OPT_ENVIRON = 256,
  OPT_RESOLVE
};

/* Indented using indent-region.  */
enum
  {
    OPT_ENVIRON = 256,
    OPT_RESOLVE
  };

/* Indented using indent-region.  */
enum {
  OPT_ENVIRON = 256,
  OPT_RESOLVE
};

For structs,

static struct argp_option argp_options[] = {
  { "debug", 'd', NULL, 0,
    "turn on debugging, run in foreground mode", GRP + 1 },
};

/* Indented using indent-region.  */
static struct argp_option argp_options[] = 
{
  { "debug", 'd', NULL, 0,
    "turn on debugging, run in foreground mode", GRP + 1 },
};

/* Indented using indent-region.  */
static struct argp_option argp_options[] =
  {
    { "debug", 'd', NULL, 0,
      "turn on debugging, run in foreground mode", GRP + 1 },
  };

With and without a space prefix inside the internal curlies.
