Having space in desktop name (and rule, but I haven't gotten the desktop to work yet) 
I'm having a space in the desktop name when trying to do rules

    bspc rule -a firefox desktop=foobar &lt;-- works 
    bspc rule -a firefox desktop=foo bar &lt;-- doesn't work
    bspc rule -a firefox desktop='foo bar' &lt;-- doesn't work
    bspc rule -a firefox desktop=foo\ bar &lt;-- doesn't work
    bspc rule -a firefox desktop='foo\ bar' &lt;-- doesn't work

at which point my knowledge of different quoting rules comes to a halt....

Any suggestions?
