Subject: bug#42913: [PATCH] Fix issues with OpenPGP header
Date: Tue, 18 Aug 2020 15:21:53 +0200

[Message part 1 (text/plain, inline)]

Hi,

I submitted a patch a few months ago, to generate OpenPGP headers, that
seems like it was a bit faulty. When trying it out today, it didn't seem
to work properly, so I debugged it and made a few changes attached
below.

My appologies for not testing the patch thoroughly enough. I hope
everything is fixed now.
