I can't reproduce the problem with this simple setup: git init echo content >file && git add file git commit -F- <<-\EOF the subject the body Cc: Stable <stable@xxxxxxxxxxxxxxx> [4.8+] EOF If I then run: git send-email -1 --to=peff@xxxxxxxx --dry-run I get: /tmp/MH8SfHOjCv/0001-the-subject.patch (mbox) Adding cc: Jeff King <peff@xxxxxxxx> from line 'From: Jeff King <peff@xxxxxxxx>' (body) Adding cc: Stable <stable@xxxxxxxxxxxxxxx> [4.8+] from line 'Cc: Stable <stable@xxxxxxxxxxxxxxx> [4.8+]' Dry-OK. Log says: Sendmail: /usr/sbin/sendmail -i peff@xxxxxxxx stable@xxxxxxxxxxxxxxx From: Jeff King <peff@xxxxxxxx> To: peff@xxxxxxxx Cc: "Stable [4.8+]" <stable@xxxxxxxxxxxxxxx> Subject: [PATCH] the subject Date: Mon, 10 Oct 2016 17:44:25 -0400 Message-Id: <20161010214425.9761-1-peff@xxxxxxxx> X-Mailer: git-send-email 2.10.1.527.g93d4615 Result: OK So it looks like it parsed the address, and shifted the "4.8+" bit into the name, which seems reasonable. Does my example behave differently on your system? If not, can you see what's different between your real-world case and the example? It might also be related to which perl modules are available. We'll use Mail::Address if you have it, but some fallback routines if you don't. They may behave differently. Alternatively, if this used to work, you might try bisecting it. -Peff
