We should probably match Kakoune here to special-case shell commands. This would fix issues like #7752

We do still want to do command expansion for shell commands but kakoune does that tok so matching whatever they do should work

I find the escaping rules incomprehensible and end up just putting everything into a script even for small one-liner commands, so that I could just do :sh /path/to/script. I would very much welcome just executing shell commands verbatim, except for expansions ofc.
