Support for redirect pages/markup

[neilc@…]

I think a useful feature would be the ability to define "redirect pages": pages in the wiki that are implemented merely as redirects to another page.

The need for redirects arises when a page is deleted or renamed, and you don't want to orphan any links that may exist to the old page's name. Another use is for a single wiki page that describes multiple related subjects, or for a page name with several comment variants (for example, the plural of the page's name).

I find people often create wiki pages that are effectively manual redirections: they just say "See ThisOtherPage? for more information." This feature would just be automatic support for these sorts of pages. A wiki page would have a set of aliases -- pages that redirect to the page. Mediawiki implements this by a special markup tag, but that's not the only way to go.

There are related tickets: see #976 for the original request for this. I think that it would be possible to write a Redirect macro, but some support has to be added in the core so that it's easily possible to edit the page that contains the redirection.
