From 6d4c05785946e302e611be9ac1f5ca0b5ada9214 Mon Sep 17 00:00:00 2001 From: Brandon Williams Date: Wed, 16 May 2018 15:57:51 -0700 Subject: refspec: introduce struct refspec Introduce 'struct refspec', an abstraction around a collection of 'struct refspec_item's much like how 'struct pathspec' holds a collection of 'struct pathspec_item's. A refspec struct also contains an array of the original refspec strings which will be used to facilitate the migration to using this new abstraction throughout the code base.
