[Boost-build] generators.register-composing signature

Is anyone else having trouble accessing the source archive at  sourceforge?    Otherwise, I'd submit this request as a  diff.
  
  I have a need for a change to generators.register-composing, namely, to  allow for no arguments to source-types parameter.  In other words,  change:
  
  rule register-composing ( id : source-types + : target-types + : requirements * )
  
  to:
  
  rule register-composing ( id : source-types * : target-types + : requirements * )
  
  The need for this came about in writing a rule set that stages ftp  transfer of files that have changed since a target marker file was last  written.  This is a composing scenario where source files can be  of any type or of no known type.  Thus the need to say:
  
  generators.register-composing mytoolset.ftp : : FTP ;
  
  where FTP is the type I declared for the marker file.  The  requested signature exists already for rule  generators.register-standard:
  
  rule register-standard ( id : source-types * : target-types + : requirements * )
  
  Is there a good reason not to do this for register-composing?
  
  Thanks,
  Mark
