# [PATCH 1/4] git-am --whitespace: do not lose the command line option 7 messages from 2008-12-05 to 2008-12-05. Participants: Junio C Hamano, Johannes Schindelin. Thread: https://gitlist.dev/t/16602 ## Junio C Hamano, 2008-12-05 02:22 Subject: [PATCH 0/4] Fix longstanding "git am" bug Message-ID: <1228443780-3386-1-git-send-email-gitster@pobox.com> URL: https://gitlist.dev/e/1228443780-3386-1-git-send-email-gitster%40pobox.com ``` Simon Schubert rerolled a patch to add "git am --directory=" from three months ago, which is a good complement to existing "git am -p", but it had the same issue of duplicating an existing bug to the new feature. Let's fix the existing bug first, before accepting any new feature, which will happen after 1.6.1 goes final.

The breakage was introduced by the commit 67dad68 (add -C[NUM] to git-am, 2007-02-08); this should fix it.

Because a series of patches applied in the same "git am" run tends to come from the same source, it is more useful to propagate these options after the application stops.
