Hi, thanks for the heads-up. Reverted in guix master commit 7d440cdbfdf6f2164895d448fe3e5bfce1ce4ea2 and then fixed correctly (manually) in guix master commit 219612904c005328d892aaf9737c37a91635db2a. Good to know that such a thing can happen with git am. I was of the impression it would check the git commit ids before patching--but apparently not O_o Thanks again.
