plugin not working on lightweight checkouts

[Chris Hecker]

I've got this simple plugin that updates a file named 'revno' with the 
revno and revid at the root of a branch when a checkin or pull happens 
so I can use it in my build system. It works great, and it's below. But, 
I was on another machine that has a lightweight checkout of this project 
and it does not appear to update 'revno' when I push to the repo for 
this branch remotely, and then update the working copy. Is there 
anything I can do to fix this easily?

I didn't immediately see another hook at 
http://doc.bazaar.canonical.com/bzr.dev/en/user-reference/hooks-help.html that 
would help, but I admit I skimmed it...

Thanks,
Chris




"""Update the "revno" file when the branch changes.
