Item10991: I18N.pm still causes warnings because of uninitialized $tag under perl 5.12

Item10267 meant to fix this, but

lc($tag || '')

still causes errors in apaches errorlog when using perl 5.12. However

lc(($tag || ''))

will work as do

$tag = shift || '';
$tag = lc($tag);

and of course

    sub _normalize_language_tag {
        my $tag = shift;
        if ( not $tag ) { return '' }  # fix
        $tag = lc($tag);

from that item. I suppose the same is true for lib/Foswiki/UI/Save.pm line 495

    my $editaction = lc( $query->param('editaction') || '' );

and lib/Foswiki/UI/Edit.pm line 48

    my $editaction = lc( $query->param('action') || '' );

altough I've never seen anything in my logs about them.

I really don't think this is important, and it's not something I've seen in the logs when working on 1.2.0 under 5.14, so marking as no-action.
