Hmm...looks like the lvm2 format plugin in EVMS does check for spaces when 
creating a new VG or LV, but the lvm1 format plugin does not. I've added a 
patch to fix the lvm1 plugin. Sorry for the trouble. :(  I guess this case is 
sufficiently unusual that no one has hit before, or at least not mentioned it 
to me before.
