[Boost-build] [bbv2] Only conditional sources, bug?

This gives an error:

lib foo : :
   <os>NT:<source>pita_win32.cpp
   <os>LINUX:<source>fun_with_linux.cpp
   ;

Because of the lack of entries in the sources spec. Which made me resort to:

lib ~foo~NT :
   pita_win32.cpp
   :
   <os>LINUX:<build>no
   ;

lib ~foo~LINUX :
   fun_with_linux.cpp
   :
   <os>NT:<build>no
   ;

alias foo : :
   <os>NT:<library>~foo~NT
   <os>LINUX:<library>~foo~LINUX
   ;

Obviously I would prefer the first one for many reasons :-) Since 
overall this is possible with the use of the alias. Why isn't it 
possible in the more direct form? Or is it a bug?
