[boost] [git] Some headers are executable

Hi, I've just checked out git and ran b2 headers and noticed that some headers have executable attribute. For example: $ find boost -executable -type f boost/pointee.hpp boost/assign.hpp boost/graph/vf2_sub_graph_iso.hpp boost/indirect_reference.hpp boost/parameter.hpp boost/detail/indirect_traits.hpp boost/detail/is_xxx.hpp boost/range.hpp This was not the case with svn. Is this the result of the transition? Can this be fixed?
