[PATCH] Add colour support in rebase and merge tree diff stats output.

[PATCH] Add colour support in rebase and merge tree diff stats output.

[James Bowes]

The rebase and merge commands used diff-tree to display the summary stats of
what files had changed from the operation. diff-tree does not read the
diff ui configuration options, so the diff.color setting was not used.

Have rebase and merge call diff rather than diff-tree, which does read the
diff ui options.

I'm not sure if setting GIT_PAGER to '' is the best way to disable the pager
in this case (though I'm quite certain it should be disabled), but it does
the trick. Perhaps there should be a git --no-pager option?
