I'm not able to apply your patch. Could you send the patches made

"all" is the default target, isn't it? In the interest of brevity, you
can drop it.

There should be two spaces after the full stop '.' at the end of a
sentence. Do run through 'guix lint'. It will warn you about this.

This comment is only for emacs-xelb, and shouldn't be here, right?

Everything else LGTM. Please send one last patch set. There may be a few
more minor corrections. I'll make them and push. I'm eager to try out
exwm. I didn't know about it before your patch. Thank you! :-)
