getQILL methods localisation

The getQILL methods in CRM/History/Selector.php and CRM/Contact/Selector.php build a ?human? language expansion of the search query. Unfortunately, they contain constructs like

$patternOr = "/(.*) or$/";
[...]
$str = 'Contact Type -';
if ($fv['cb_contact_type']) {
foreach ($fv['cb_contact_type'] as $k => $v) {
$str .= " {$k}s or";
}
$str = preg_replace($patternOr, $replacement, $str);
} else {
$str .= ' All';
}

which can be next to impossible to localise (not to mention pushing regexps to translators is always risky).
