From 431b1969fcde69959a23355fba6894fb69c8fa0c Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Sat, 21 Mar 2009 12:51:34 -0700 Subject: Rename interpret/substitute nth_last_branch functions These allow you to say "git checkout @{-2}" to switch to the branch two "branch switching" ago by pretending as if you typed the name of that branch. As it is likely that we will be introducing more short-hands to write the name of a branch without writing it explicitly, rename the functions from "nth_last_branch" to more generic "branch_name", to prepare for different semantics.
