From 063da62b02aeafe58fdacce0ea48c0761b06df60 Mon Sep 17 00:00:00 2001 From: Christian Couder Date: Mon, 7 Jul 2014 08:35:37 +0200 Subject: [PATCH] commit: add for_each_mergetag() In the same way as there is for_each_ref() to iterate on refs, for_each_mergetag() allows the caller to iterate on the mergetags of a given commit. Use it to rewrite show_mergetag() used in "git log".
