Subject: Properly handle empty addresses (<>) when they show up in mail
X-Git-Tag: mutt-1-5-2-rel~85
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=a7e19b306abd48b460c756b79b0b801fba011193;p=mutt

Properly handle empty addresses (<>) when they show up in mail
headers.  The approach taken is to store this address as <@>, and to
check this special case when printing an address.
