From 69b1cf91e50808df4424c563b1256665034baec8 Mon Sep 17 00:00:00 2001 From: Karthik Nayak Date: Sun, 14 Jun 2015 01:07:26 +0530 Subject: ref-filter: add 'ref-filter.h' This is step one of creating a common library for 'for-each-ref', 'branch -l' and 'tag -l'. This creates a header file with the functions and data structures that ref-filter will provide. We move the data structures created in for-each-ref to this header file.
