clang-format poor spacing with braces initializer

[cmcqueen]

test.c containing:

static const CMD_HANDLER_T command_handlers[] =
{
    {   "a",            HandleA             },
    {   "bb",           HandleBB            },
    {   "ccc",          HandleCCC           },
    {   NULL,           NULL                },
};

Command:

clang-format -style="{ SpacesInParentheses: true, AlignArrayOfStructures: Left }" test.c > test.out.c

Result:

static const CMD_HANDLER_T command_handlers[] = {
    {"a",    HandleA  },
    { "bb",  HandleBB },
    { "ccc", HandleCCC},
    { NULL,  NULL     },
};

Anomalous things:

• For the first row only, there is no space between the opening brace and the first value.
• For the row with the widest last value, there is no space between the last value and the closing brace.

I have tested this with Clang-Format v13.0.1, v15.0.7 and v16.0.0, with the same results.

Same issue here, is there any progress on this? It's pretty annoying...

I've also run in to this bug while migrating an old project to git and cleaning up its formatting.

I hit this one, too. clang-format 16.0.6.

Could you please try 17 or main branch?

Still happens on 17.0.6
