Ok, I dodn't know that - thanks for pointing it out. In my setup here,
SSIDs are always valid alphanumeric strings, and I was mislead by the
comment that mentions the NULL-termination.

Those macros are stubbed out as nops in my setup, so they can
unfortunately not be the reason. I'll dig deeper :)
