Subject: [PATCH 2/9] git: modified: don't slurp `rev-parse --branches'
Date: Sat, 11 Jan 2020 22:34:56 +0000
Message-ID: <20200111223503.24473-3-e@yhbt.net> (raw)
In-Reply-To: <20200111223503.24473-1-e@yhbt.net>

While v1 inboxes typically only have one branch, code repositories
may have dozens or even hundreds.  Slurping those into memory is
a waste.
