The Git documentation pages hosted at kernel.org are a bit over a year out of date ("Last updated 2013-02-15 19:24:31 UTC") - so from around Git v1.8:
https://www.kernel.org/pub/software/scm/git/docs/
Are they fiddly to update? Should they be updated in celebration of Git 2.0, or maybe instead redirect to http://git-scm.com/docs ?
