Broken links to selenic.com

[Stanimir Stamenkov]

[Resending to mercurial at mercurial-scm.org]

Looks like there are quite a few broken links currently pointing to 
selenic.com, like:

http://www.selenic.com/hg/help/revsets

These appear in Google searches:

https://www.google.com/search?q=hg+revsets

and used on the Mercurial Wiki:

https://www.mercurial-scm.org/wiki/MercurialTips?highlight=%28revsets%29

It would have been nice to have these operational, redirecting using 
"HTTP 301 Moved Permanently" for some time before making them 
completely defunct, but seems I can't find what would be the new 
link for the "revsets" example.  The Wiki content needs an update at 
least.
