Subject: [RFC/PATCH] ls-remote: optionally return non-zero on non-existing refs
Date: Wed, 18 May 2011 16:15:44 +0200	[thread overview]
Message-ID: <4DD3D490.1090503@elegosoft.com> (raw)
In-Reply-To: <7vk4dvdg6x.fsf@alter.siamese.dyndns.org>

git ls-remote returns zero no matter if the given references were found
or not. Teach ls-remote an option --exit-status to make it optionally
returning a non-zero status.

Signed-off-by: Michael Schubert <mschub@elegosoft•com>

If there is just one existing ref in a list of non-exising refs, this will
return zero though - as "git show-ref" does.
