D6789: check-code: allow command substitution with $(command)

[spectral (Kyle Lippincott)]

spectral added a comment.


  This shouldn't be about the user's chosen shell, though, right? This is about the `/bin/sh` implementation, which you wouldn't/can't replace with fish, so I think it won't bother users that use fish, just distros with really old implementations of /bin/sh.
