Back (or HEAD) link in Wiki history page.
When displayed Wiki page, one can press History link to view wiki revisions. In this revisions page, there is no link back to the wiki page. Yes, there are links to all of the revisions but they go to URLs that include revision number. I think it would be good to have link back (despite of the browser's "back" button). This link could be placed atop of the revision list and its name could be "Page" or "HEAD" par example.
