At present, if you want to remove one specific version from editing history, you
have to (1) delete the entire page, then (2) undelete, and check the box for
EVERY VERSION other than the one you want gone. Needless to say, for pages with
any kind of history, this is highly impractical.

Also, the Special:Undelete page lists ALL versions, even if there's hundreds;
most such pages cut off at fifty and give a "more" button.

Thus, it would be nice to be able to delete individual versions, possibly from
the History Log page. Failing that, it would at least be nice to add a button to
the Special:Undelete page that checks all checkboxes in a single click (and you
can then uncheck the ones you don't want)
