**Describe the issue**

```
github-explorer.ru-central1.internal :) ALTER TABLE hackernews MODIFY COLUMN text CODEC(ZSTD), MODIFY COLUMN title CODEC(ZSTD), MODIFY COLUMN url CODEC(ZSTD)

ALTER TABLE hackernews
    MODIFY COLUMN `text` CODEC(ZSTD),     MODIFY COLUMN `title` CODEC(ZSTD),     MODIFY COLUMN `url` CODEC(ZSTD)
```

See that weird indentation without newlines?
settings.ostr << (settings.hilite ? hilite_keyword : "") << indent_str
                      << "MATERIALIZE COLUMN " << (settings.hilite ? hilite_none : "");
        column->formatImpl(settings, state, frame);
        if (partition)
        {
            settings.ostr << (settings.hilite ? hilite_keyword : "") << indent_str << " IN PARTITION " << (settings.hilite ? hilite_none : "");
            partition->formatImpl(settings, state, frame);
        }
    }
    else if (type == ASTAlterCommand::COMMENT_COLUMN)
    {
        settings.ostr << (settings.hilite ? hilite_keyword : "") << indent_str << "COMMENT COLUMN " << (if_exists ? "IF EXISTS " : "") << (settings.hilite ? hilite_none : "");
