Subject: [PATCH v3 5/6] fetch: reduce duplicate in ref update status lines with { -> }
Date: Sun, 5 Jun 2016 10:11:40 +0700 [thread overview]
Message-ID: <20160605031141.23513-6-pclouds@gmail.com> (raw)
In-Reply-To: <20160605031141.23513-1-pclouds@gmail.com>
Most of the time, ref update lines are
variable-long-name -> fixed-remote/variable-long-name
With fetch.output set to "compact" such a line will be shown as
{ -> fixed-remote}/variable-long-name
This keeps the output aligned (because the variable part is always at
the end) and reduce duplication.
