Hi Gábor,

The spdlog package contains a bundled fmt library.  I tried to unbundle
fmt before, but the maintaining work does not worth it.  This patch
clarify it's license.

I notice you pushed several Sway related packages into the master
branch, but none of them has been submitted to the mailing list.  Would
you please send you patches to the mailing list first in the future?

You also pushed mako into master, but there is already a discussion
about mako here:
https://lists.gnu.org/archive/html/guix-patches/2019-03/msg00567.html.
We should build mako from it's git master or wait until the next point
release.
