From b0ad11ea165e07308fc02a5091efbe2e2d22237c Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Tue, 14 Oct 2008 15:32:20 -0700 Subject: [PATCH] pull: allow "git pull origin $something:$current_branch" into an unborn branch Some misguided documents floating on the Net suggest this sequence: mkdir newdir && cd newdir git init git remote add origin $url git pull origin master:master "git pull" has known about misguided "pull" that lets the underlying fetch update the current branch for a long time. It also has known about "git pull origin master" into a branch yet to be born. These two workarounds however were not aware of the existence of each other and did not work well together. This fixes it.
