As far as I know, it is perfectly possible to have LF/CR in a path
name (that's bad practice btw...), and your patch would make initdb
fail in such cases. Do we want to authorize that? If we bypass the
error checks in appendShellString with an extra option, and have
initdb use that, the generated command would be actually correct.
