The 'eval' introduced in #262 unfortunately breaks command
invocations were a parameter contains spaces, such as
rg "my pattern with spaces"
as it would be called as `rg my pattern with
spaces`. This can be fixed using printf. Using
parameter extension quoting with ${@@Q} only
works with bash >4.4 (but only >4.0 is required).
At least the above invocation then works correctly!
