Use `git diff a b` for ranges, not `git diff a..b`

Authored by epriestley on Jul 11 2014, 4:57 PM.



These are documented as being identical, but git diff a b works if a is a tree (for example, 4b825d..., the empty tree hash), but git diff a..b does not.

Particularly, with the a..b form, arc diff --base arc:empty does not work. With the a b form, it does.

Test Plan

Ran arc diff --base arc:empty in a repository and got a diff.
