This like busts the 80 characters limit.  You can break it with a
backslash (\) followed by a newline, e.g.

--8<---------------cut here---------------start------------->8---
                (url "https://skia.googlesource.com/external/github.com\
/KhronosGroup/SPIRV-Headers.git")
--8<---------------cut here---------------end--------------->8---

I think 'guix lint' warns about this.
