[PATCH v3] git-am: fix maildir support regression: accept email file as patch
From: Nicolas Sebrecht <hidden>
Date: 2016-06-15 22:47:03
Patch format detection introduced by a5a6755a1d4707bf2fab7752e5c974ebf63d086a may refuse valid patches. We keep detection on the first three lines. Emails may have: - header fields in a random order; - folded lines. Signed-off-by: Nicolas Sebrecht <redacted> --- git-am.sh | 17 +++++++++++++++++ 1 files changed, 17 insertions(+), 0 deletions(-)
