From 67d176300c0a79d5cf65402c641fcec7c5388f29 Mon Sep 17 00:00:00 2001 From: Hitoshi Mitake Date: Fri, 12 Feb 2010 20:36:12 +0900 Subject: git-imap-send: Convert LF to CRLF before storing patch to draft box When storing a message over IMAP (RFC 3501 6.3.11), the message should be in the format of an RFC 2822 message; most notably, CRLF must be used as a line terminator. Convert "\n" line endings in the payload to CRLF before feeding it to IMAP APPEND command.
