wp_title uses tag slug, not tag name

[ionfish]

When viewing a tag archive page, the wp_title function outputs the tag slug (i.e., "john-doe") rather than the tag name (i.e., "John Doe").

Shouldnt this be going into 2.3? Afterall, we're still fixing bugs.

Yes, that's why I submitted it now, since Ryan said "From now on we’re concentrating exclusively on testing and bug fixing."

It's also the most minor of minor patches, so I figured it would easily get into the release. :)
