How can I make a fieldset legend-style “background line” on heading text?

Question

I\'m attempting to style heading text similar to how your default legend text appears in fieldsets; that is to say, I\'d like a strikethrough-like line to come up to, but no

This doesn't feel like a very good answer, but I'm posting it anyway.

See: http://jsfiddle.net/rFmQg/

Centered Header Text

h2 {
    background: url(http://dummyimage.com/2x1/f0f/fff&text=+) repeat-x center;
    text-align: center
}
h2 span {
    background: #fff;
    padding: 0 9px
}

I don't like it because:

• You have to use an image.
• This. (it only works if the backgrounds match)
