[PATCH v5 07/15] remote: die on config error when setting URL

From
Patrick Steinhardt <ps@pks.im>
Date
Feb 16, 2016, 12:56 UTC
Message-ID
<1455627402-752-8-git-send-email-ps@pks.im>
In-Reply-To
<1455627402-752-1-git-send-email-ps@pks.im>

When invoking `git-remote --set-url` we do not check the return value when writing the actual new URL to the configuration file, pretending to the user that the configuration has been set while it was in fact not persisted.

Fix this problem by dying early when setting the config fails.
