Comment:

 Detecting redirects is tricky.  And it can't be done on the fly -- too
 slow.  Perhaps it could be done when you update your General settings.  I
 don't know if this is widespread enough to justify all that code.  I'd
 think that people who want a canonical domain would be consistent about it
 and not choose a web host redirect feature that points to the opposite of
 what they use on their blog.

 Simple idea of how it could work on the General settings page: when you
 submit the form, WP does an HTTP HEAD on the main page of the blog, and
 determines if a 30x is returned to a new domain.  If so, it updates the
 domain in {{{siteurl}}} and {{{home}}} -- maybe tells the user why the
 setting was overridden.
