[Boost-build] type.set-generated-target-prefix with empty string does not work to remove prefix

Hi,

I'm trying to work with a custom generator on a linux system and 
recently upgraded my boost-build v2 from an older version to a cvs 
version from about a week ago.  (I obtained the cvs version by clicking 
on the nightly build link on the boost-build v2 home page if that matters).

The custom generator I have is based on SHARED_LIB and it seems that one 
of the newer things implemented in boost-build is that, on unix systems, 
a "lib" prefix is added to all such libraries.  I understand the 
rationale for that, but for my application, the prefix does not make 
sense.  After poking around in type.jam I found the 
type.set-generated-target-prefix command.  The comments before this 
function imply that I can use an empty string to effectively remove the 
prefix.  However, it does not work for me.  Is this a bug or is the 
comment out-dated?

For example,

    type.set-generated-target-prefix MEXLIB : : "asdf" ;

works fine, but

   type.set-generated-target-prefix MEXLIB : : "" ;

does not.  Any help would be appreciated,

Thanks,

Jordan
