This one is also whitespace damaged.. Could you please explain why this
change is needed? wpa_supplicant stops scanning if there are no enabled
networks.

Is this correct? This is removing just one network and there could be
other enabled networks that are being scanned.

Sorry for that, It's a side effect from my Windows machine that I'm using for Emails. I'll fix it.

It's especially needed for scheduled scan, but we can stop the regular scans as well.
