Loading extensions at hgwebdir index?

[Brodie Rao]

Is it possible to have extensions loaded at the hgwebdir repository  
index?
As far as I can tell it currently only loads extensions when an  
individual
repository is loaded. Is this behavior intentional?

To be more specific, I have an extension that allows the user to apply
settings for multiple repos in a single hgrc. This works fine for  
everything
but setting the contact, description, etc. in the repository index.  
Mercurial
doesn't load the extension at that point.
