Subject: bug#36301: Package-Requires should support multiple lines
Date: Wed, 19 Jun 2019 21:55:27 -0400

Hi,

The Package-Requires line in my GNU ELPA package, Excorporate, is much
longer than 80 characters and I would like to wrap it.  It would be nice
if package.el allowed Package-Requires to span multiple lines (see
patch).  It's probably too late to change this but I thought I'd file a
bug report anyway.

Thomas
