[TYPO3] Backend Configuration - Alternate Page Language

[Erik Weber]

I recently added these lines to my extTables.php to expand the title and
subtitle inputs on my pages:

// Add a second line to the pagetitle field
$GLOBALS['TCA']['pages']['columns']['title']['config']['type'] = 'text';
$GLOBALS['TCA']['pages']['columns']['title']['config']['cols'] = '30';
$GLOBALS['TCA']['pages']['columns']['title']['config']['rows'] = '2'; 
// Add a second and third line to the subtitle field
$GLOBALS['TCA']['pages']['columns']['subtitle']['config']['type'] = 'text';
$GLOBALS['TCA']['pages']['columns']['subtitle']['config']['cols'] = '50';
$GLOBALS['TCA']['pages']['columns']['subtitle']['config']['rows'] = '3'; 

The question is, what do I change 'pages' to to do the same for my alternate
page language pages so that I can have multi-line titles and subtitles in
both languages?
