[PATCH 3/3] diffstat generation in hooks--update was passing "^baserev" to git-diff-tree

[Andy Parkins <andyparkins@gmail.com>]

For generating the diffstat after a branch update, git-diff-tree is
simply comparing the new revision with the base revision.  However, the
baserev was being passed with a "^" operator proceeding it - this (I
think) made git-diff-tree think that a path was being specified for
comparison rather than a second path, so only a single revision was
being summarised.
