"Found at least @count files" text not styleable

@solideogloria

the message style looks good in claro theme in my sytem.

The important thing is that the text isn't in an element, so it can't be styled. If the padding is good in some other theme, fine, but there's no way for me to style the text when it doesn't look good in my theme.

Hi there,

I replaced the regular markup with the html_tag type.
