[boost] [filesystem] Decomposition of filenames beginning with period?

Boost.Filesystem class path views filenames as being made up of a stem and an extension. My Windows Users directory includes files ".gitconfig" and ".netrc". The current class path implementation views these as having extensions of ".gitconfig" and ".netrc", respectively, and empty stems. To me, that's a bit counter intuitive. I guess I view filenames as always having stems, but extensions being optional. But I don't view that as a strong enough argument to change anything. Does anyone have a stronger argument than intuition for changing or retaining the current behavior? --Beman
