I installed vim from homebrew-alt, then installed it again:

````
$ brew install -v ./duplicates/vim.rb
==> Cloning https://vim.googlecode.com/hg/
Updating /Users/adamv/Library/Caches/Homebrew/vim--hg
hg pull
warning: vim.googlecode.com certificate with fingerprint 88:4d:f4:03:d3:c0:1a:be:50:f3:7a:c9:76:5c:38:87:59:19:49:78 not verified (check hostfingerprints or web.cacerts config setting)
pulling from https://vim.googlecode.com/hg/
searching for changes
no changes found
Error: Failure while executing: hg pull
````

Hg is returning an error if there are no changes, which system is detecting as a failure.

This is new behavior in Hg 2.1, and is breaking other projects as well.
