[Boost-build] bug in build-system.jam autoconfigure ?

The "Autoconfigure" code in build-system.jam has the behaviour to strip the 
version apart from the toolset. The code strips everything to the right of the 
first hyphen to be the version.

I.e.:
         local (t-v,t,v) = [ MATCH (([^-/]+)-?([^/]+)?)/?.* : $(t) ] ;

This has the consequence, that it is impossible to put subfeatures into build 
requests on the commandline:

bjam toolset=gcc-3.4.4-mingw

tries to register a new version of the gcc toolset instead of recognizing it as 
a subfeature (i.e. flavor) of the gcc toolset.

The following request (which skips the autoconfigure) instead works:

bjam gcc-3.4.4-mingw

Is this by intent or is it a bug?
