[PATCH v5 08/15] remote: die on config error when setting/adding branches

From
Patrick Steinhardt <ps@pks.im>
Date
Feb 16, 2016, 12:56 UTC
Message-ID

<1455627402-752-1-git-send-email-ps@pks.im>

When we add or set new branches (e.g. by `git remote add -f` or `git remote set-branches`) we do not check for error codes when writing the branches to the configuration file. When persisting the configuration failed we are left with a remote that has none or not all of the branches that should have been set without notifying the user.

Fix this issue by dying early on configuration error.
