Of course you may not be talking about DNS -- but I'm pretty sure that
under DNS legal hostname characters are [a-z0-9.-] (case insensitive)
which doesn't include space.

A text-based config file format that includes significant whitespace
as you suggest and doesn't delimit it (eg, with quotes) is asking to
be derided. Just look at make(1).
