From 173aef7c2ee9aa0021dad7c70d30f9099be4a134 Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Wed, 14 Oct 2015 15:40:04 -0700 Subject: mailinfo: move global "FILE *fin, *fout" to struct mailinfo This requires us to pass "struct mailinfo" to more functions throughout the codepath that read input lines. Incidentally, later steps are helped by this patch passing the struct to more callchains.
