[PATCH 0/1] git-config --add allows values from stdin

[Zeger-Jan van de Weg <git@zjvandeweg.nl>]

When adding or updating configuration values using git-config, the
values could all be observed by different processes as these are passed
as arguments. In some environments all commands executed are also all
logged. When the value contains secrets, this is a side effect that
would be great to avoid. At GitLab we use Rugged/libgit2 to circumvent
this property[1].

The following patch allows a value to be set through stdin when the user
passes a `--stdin` flag.
