Bridged topic names with spaces in mosquitto.conf

[viktorkho]

Seems that it is impossible to setup bridging of topics,
Seems that it is impossible to configure bridging of topics containing spaces, eg:

/sensors/DS 1
/sensors/DS 2
/sensors/..
/sensors/DS 32

I tried to configure it like this:

# This works fine but produces unwanted traffic:
topic /sensors/# out 1

# This all doen't work:
topic /sensors/DS\ 4 out 1
topic '/sensors/DS 4' out 1
topic "/sensors/DS 4" out 1

but fail with Error: Invalid bridge topic direction '4' on my mosquitto version 1.4.15

Is it possible to add spaces escaping in this place?
