[Bf-committers] Crease in multires

I'm not sure this should really be considered a show-stopper bug.
Remember that multires (unlike subsurf) can be edited at higher
levels, so it is possible to crease the mesh (just not automatically.)
Moreover, this has rarely come up as a critical problem from users
testing multires.

This is not to say it's not a desirable feature, but it's a little
late in the release cycle to mess around with issues like this. I
would suggest this issue be put on the todo list for the next release.
