[OSSTEST PATCH 5/5] mg-list-all-branches: Do not match ${BRANCHES+= ... }

[Ian Jackson <ian.jackson@eu.citrix.com>]

This is not valid shell syntax and should not appear.  The confusion
seems to have arisen because of the need for to match BRANCHES+=...
(without the surrounding { }).

This results in no change to the output.  (I seem to have collected
this patch some time ago as part of some fixes to mg-list-all-branches
which have by now been applied, but not managed to write up and post
this specific change.)
