Some minor changes to make the code more consistent

1. Syntax error in string:
includes/webform.emails.inc

function webform_email_edit_form($form_state, &$node, $email = array()) {
...
      case 'subject':
        $default_value = _webform_filter_values(webform_variable_get('webform_default_subject'), $node);
        $title = t('E-mail subject');
-        $description = t('Aany textfield, select, or hidden form element may be selected as the subject for e-mails.');
+        $description = t('Any textfield, select, or hidden form element may be selected as the subject for e-mails.');

2. Slightly inaccurate attribute value (it's allowed, but not recommended):
the same function, a bit lower

  // TODO: Allow easy re-use of existing templates.
  $form['templates']['#tree'] = TRUE;
  $form['templates']['default'] = array(
    '#type' => 'textarea',
    '#value' => $default_template,
-    '#attributes' => array('style' => 'display: none'),
-    '#attributes' => array('style' => 'display: none;'),
    '#resizable' => FALSE,
  );

3. Small mistake in comments:
includes/webform.admin.inc

/**
- * Menu callback for admin/webform/settings.
+ * Menu callback for admin/settings/webform.
 */
function webform_admin_settings() {
