Update on shared content multisite gives errors

An update from RC to 6.x-1.0 on a shared content multisite gives the usual gamut of warnings about tables that have been updated already. This is not a huge problem - it's an edge case.

It does reveal though that line 136 of i18ncontent module has an error that will affect anyone with a renamed table, which is common on shared hosting.

The error:

* user warning: Table 'test_update.node_type' doesn't exist query: UPDATE node_type set help = '' WHERE type = 'ad/html' in /var/www/sites/all/modules/i18n/i18ncontent/i18ncontent.module on line 136.

The problem is that

db_query("UPDATE node_type set help = '' WHERE type = '%s'", $info->type);

Should read

db_query("UPDATE {node_type} set help = '' WHERE type = '%s'", $info->type);
