I asked Tony to package this up, and he did so.  Tonight I committed
the code to r-devel, so it should show up in 1.9.0.

I'd appreciate it if people would try out the new code, which shows up
as new entries in the Edit and popup menus in the console and the file
viewing windows.  It's easy to overlook something when fiddling with
the GUI.

This will show up by Monday in the binary builds that appear on CRAN.
Remember to follow the link to the development build.
