From c22e7de340df2e0ebc0e98347aa02a32a459835f Mon Sep 17 00:00:00 2001 From: Jeff King Date: Wed, 23 Feb 2011 04:59:18 -0500 Subject: [PATCH] format-patch: rfc2047-encode newlines in headers These should generally never happen, as we already concatenate multiples in subjects into a single line. But let's be defensive, since not encoding them means we will output malformed headers.
