You can use [ feature.values <toolset-msvc:version> ] to
get a list of all known versions of msvc.

I have no idea why that would be.  Version is used exactly
three times in msvc.configure-version-specific.
[ MATCH ^(6\\.) : $(version) ]
[ MATCH ^([78]\\.) : $(version) ]
[ MATCH ^([67]) : $(version) ]
These should all fail to match regardless of whether
you use 10 or 10.0.  It does matter for 8.0 obviously,
but even then the behavior shouldn't depend on whether
you've initialized msvc.

(Note: I'm working with the current develop branch
in git.  Please indicate the exact version of Boost.Build
that you are using.)
