From aebfc13337e503b5a7d064cb1e9c9916f24c2baf Mon Sep 17 00:00:00 2001 From: Michael Haggerty Date: Mon, 7 Apr 2014 15:48:11 +0200 Subject: update-ref --stdin: reimplement using reference transactions This change is mostly clerical: the parse_cmd_*() functions need to use local variables rather than a struct ref_update to collect the arguments needed for each update, and then call ref_transaction_*() to queue the change rather than building up the list of changes at the caller side.
