Save As no longer disposes old window
Trunk has a new problem(s) -- if you File=>Save As, you end with two windows, both with the same name. Old/expected behavior was a new window opens with the user supplied new name, old window is disposed.
Also it appears that if you close the second of the two and you have no other windows open, kepler quits.
Happens at r27521 on linux and osx10.6.
