The drush command hook naming conventions have changed;

Using the HEAD version of Drush and 'drush schema-inspect' and get the error:

"The drush command hook naming conventions have changed; the function [error]
drush_schema_schema_inspect must be renamed to drush_schema_inspect.
The old function will be called, but this will be removed shortly."

The attached patch renames the drush_schema_schema_inspect() function to drush_schema_inspect().
