Whoever reads this, can I haz stamp?

lgtm. Please consider the comments inline.

File chrome/app/policy/policy_templates.json (right):

http://codereview.chromium.org/9968013/diff/1/chrome/app/policy/policy_templa...
chrome/app/policy/policy_templates.json:2577: Specifies the prefix of the prefix
of a target version <ph name="PRODUCT_OS_NAME">$2<ex>Google Chrome OS</ex></ph>
should update to. If the device is running a version that's before the specified
prefix, it will update to the latest version with the given prefix. If the
device is already on a later version, there is no effect (i.e. no downgrades are
performed) and the device will remain on the current version. The prefix format
works component-wise as is demonstrated in the following example:
s/the prefix of the prefix of/the prefix of/

http://codereview.chromium.org/9968013/diff/1/chrome/app/policy/policy_templa...
chrome/app/policy/policy_templates.json:2582: 1412.24.34: update to this
specific version only
Put these examples within quotes too, it was a bit confusing when reading this.
