This looks correctly aligned, but I'm guessing you're referring to the
newlines here?  And those do indeed look kinda superfluous.

After digging into the widget code for what seems like hours, I finally
found out what's inserting that newline (by adding a debug-on-entry on
`insert', of course).  It's this:

(define-widget 'group 'default
  "A widget which groups other widgets inside."
  :convert-widget 'widget-types-convert-widget
  :copy 'widget-types-copy
  :format ":\n%v"

But I have no idea how to override that in the context of a face
definition.  Anybody?
