Bug#1037289: reportbug: EMAIL environment variable does not work

[Stephane Bortzmeyer <stephane+debian@bortzmeyer.org>]

Package: reportbug
Version: 12.0.0
Severity: minor

Dear Maintainer,

The man page says "REPORTBUGEMAIL, DEBEMAIL, EMAIL
              Email address to use as your from address (in this order). If no environment variable exists, the default is taken
              from your user name and /etc/mailname." but EMAIL does
not work:

% env |grep MAIL
EMAIL=stephane@bortzmeyer.org

% reportbug whois

Using 'Stephane Bortzmeyer <stephane@sources.org>' as your from address.


--email on the command-line does work.
