[exim-dev] dkim header wrap

Is anyone interested in a patch to pdkim/pdkim.c to line-wrap
the generated DKIM signature header in a more tidy manner like this:

DKIM-Signature: v=1; a=rsa-sha256; q=dns/txt; c=relaxed/relaxed;
d=example.com; s=sel1; h=List-Unsubscribe:Feedback-ID:Message-ID:Subject:To:
From:Date; bh=bZQuQno5A//oTtiB4xVXdixxxxxRv++mX8r4m6xtnaQ=; b=J1lZwgSeWMpLpmR
h/t1kjRaZbtwgKShsf54YyhuEJQgnp+QZcGy6Jy4Gxxxxxonj4MOw2aBv3VMQQ34g1f154O9m+UCu
PzjxE8y1P9XBlcH9Ke8cleMI/gD5Yr59r8pIvr7q4mmjQPxxxxxbOOHIlpBfYEGFUx+cgXgaaFB2K
9g=;

Which meets more of the SHOULDs in RFC 5322 and RFC 4871

(I've actually got tab as the line continuation character but I showed
space for the purpose of posting here)
