Don't add spaces after ( in convert_comments.go.

Code like this:

    if (// Check if the cipher is supported for the current version.
        SSL_CIPHER_get_min_version(c) <= ssl3_protocol_version(ssl) &&
        ssl3_protocol_version(ssl) <= SSL_CIPHER_get_max_version(c) &&
        // Check the cipher is supported for the server configuration.
        (c->algorithm_mkey & mask_k) &&
        (c->algorithm_auth & mask_a) &&
        // Check the cipher is in the |allow| list.
        sk_SSL_CIPHER_find(allow, &cipher_index, c)) {

should not get an extra space.
