[PATCH 06/15] submodule init: redirect stdout to stderr

From
Stefan Beller <sbeller@google.com>
Date
Apr 26, 2016, 20:50 UTC
Message-ID

Reroute the output of stdout to stderr as it is just informative messages, not to be consumed by machines.

We want to init submodules from the helper for `submodule update` in a later patch and the stdout output of said helper is consumed by the parts of `submodule update` which are still written in shell. So we have to be careful which messages are on stdout.
