Subject: [PATCH 28/35] push: convert to use struct refspec
Date: Mon, 14 May 2018 14:56:19 -0700	[thread overview]
Message-ID: <20180514215626.164960-29-bmwill@google.com> (raw)
In-Reply-To: <20180514215626.164960-1-bmwill@google.com>

Convert the refspecs in builtin/push.c to be stored in a 'struct
refspec' instead of being stored in a list of 'struct refspec_item's.
