I did what I needed to do. Maybe someone else will need it.
modules/news/include
edit files storyform.inc.php and storyform.original.php
$sform = new XoopsThemeForm(_NW_SUBMITNEWS, "storyform", XOOPS_URL.'/modules/'.$xoopsModule->getVar('dirname').'/submit.php');
$sform->setExtra('enctype="multipart/form-data"');
$sform->addElement(new XoopsFormText(_NW_TITLE, 'title', 50, 255, $title), true);
replace 255 with 80
This is done for a news aggregator, as conditions have changed there.
