Display CREATE INDEX column list separated by commas with spaces

Browse source 
The column list in `CREATE INDEX` now matches the style used elsewhere,
e.g. in `TableConstraint`, which is to use spaces after commas.

```sql
-- before:
CREATE INDEX idx_name ON table_name (column1,column2,column3);
-- after:
CREATE INDEX idx_name ON table_name (column1, column2, column3);
```

When `CreateIndex` was added, there was no explanation for the lack of
spaces, so I assume it was just author preference. But standard style in
all documentation I've seen is to use spaces after commas (including
[MSSQL]'s documentation of `INCLUDE`, which copied the no-spaces style
when added).
