Hello Guix,

I have a question about license, “highlight-symbol.el” says:

--8<---------------cut here---------------start------------->8---
;; This program is free software; you can redistribute it and/or
;; modify it under the terms of the GNU General Public License
;; as published by the Free Software Foundation; either version 2
;; of the License, or (at your option) any later version.
--8<---------------cut here---------------end--------------->8---

Could we use “(license license:gpl3+)” because it says “or any later
version”?

We probably *could*, but we should not hide this fact from the end
user.  I went ahead and applied this patch after changing the license to
gpl2+ and using HTTPS for the home page.  Thanks!
