Is this something we can fix by pointing out the single quotes, or is
it better not to try that?

To make it a little clearer, we currently have more or less
implementation-defined behaviour through calling system with a string-
join'ed command.  (This is not the best way of invoking an editor, but
it works, and it also works with EDITORs like "emacsclient -c" if your
shell is Bash – which Guix System has by default.)  If we were to pull
in Gash, we could process the command line a priori and then use
system* or invoke.

What would be the way forward if we use {LINE} now?
