From 990f6e30eb00adeb8cad75c3be34c0fc9ff6abb0 Mon Sep 17 00:00:00 2001 From: Jeff King Date: Thu, 14 Apr 2011 18:18:09 -0400 Subject: [PATCH] format-patch: wrap email addresses after long names We already wrap names in "from" headers, which tend to be the long part of an address. But it's also possible for a long name to not be wrapped, but to make us want to wrap the email address. For example (imagine for the sake of readability we want to wrap at 50 characters instead of 78): From: this is my really long git name The name does not overflow the line, but the name and email together do. So we would rather see: From: this is my really long git name Because we wrap the name separately during add_rfc2047, we neglected this case. Instead, we should see how long the final line of the wrapped name ended up, and decide whether or not to wrap based on that. We can't break the address into multiple parts, so we either leave it with the name, or put it by itself on a line. Test by Erik Faye-Lund.
