From 06bf4ad1db92c32af38e16d9b7f928edbd647780 Mon Sep 17 00:00:00 2001 From: Brandon Williams Date: Wed, 5 Apr 2017 10:47:19 -0700 Subject: [PATCH] push: propagate remote and refspec with --recurse-submodules Teach "push --recurse-submodules" to propagate, if given a name as remote, the provided remote and refspec recursively to the pushes performed in the submodules. The push will therefore only succeed if all submodules have a remote with such a name configured. Note that "push --recurse-submodules" with a path or URL as remote will not propagate the remote or refspec and instead use the default remote and refspec configured in the submodule, preserving the current behavior.
