I'm somewhat confused by this comment. While some of the texlive
packages do have actual sources, the big ones (texlive, texlive-union,
...) don't. I know that computed-origin is a thing that exists, but
this would really have been overkill for me.

Will do.

The thing is, I kinda do need those prefixes, because otherwise those
files will be stored as gnu/store/<hash>-emoji-<whatever>.txt, which
feels wrong. AFAIK Guile has no string-remove-prefix.

I doubt the nature of this package will allow me to be more
descriptive, but I'll try.
