This reverts commit ff8db5a85d60b21a711f8707791119adbbcffadc. As explained in commit #2367, finally the fix above was incorrect because it causes other trouble such as this: log "192.168.100.${NODE}" "local0" being resolved to this: log 192.168.100.local0 when NODE does not exist due to the loss of the spaces. In fact, while none of us was well aware of this, when the user had: server app 127.0.0.1:80 "${NO_CHECK}" weight 123 in fact they should have written it this way: server app 127.0.0.1:80 "${NO_CHECK[*]}" weight 123 so that the variable is expanded to zero, one or multiple words, leaving no empty arg (like in shell). This is supported since 2.3 with commit fa41cb6 so the right fix is in the config, let's revert the fix. This should be backported to *some* versions, but the risk that some configs were altered to rely on the broken fix is not null. At least recent LTS should be reverted.
