Yes, though a more specific error message is a bit friendlier which is
why I sent the patch to do that.

So are people happy with this change then:

Fri May  9 10:44:55 BST 2008  Duncan Coutts <duncan at>
  * Do not display version tags

    hunk ./Distribution/Text.hs 38
    -  disp (Version branch tags)
    +  disp (Version branch _tags) -- Do not display the tags
    hunk ./Distribution/Text.hs 40
    -   <> Disp.hcat (map (\tag -> Disp.char '-' <> Disp.text tag) tags)
