From 3d730ed9b21b5397be7fa5bf89298122980b0f58 Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Mon, 14 Mar 2016 15:10:39 -0700 Subject: rerere: move code related to "forget" together "rerere forget" is the only user of handle_cache() helper, which in turn is the only user of rerere_io that reads from an in-core buffer whose getline method is implemented as rerere_mem_getline(). Gather them together.
