Edit D command issues

[rjkroege]

I opened many files in Edwood. See a different for bug for how file management got to be painful. I attempted to close them Edit X/\.(go)$/ D and it didn't work. This makes sense because D isn't implemented?

But it also crashed:

Unimplemented: main.D_cmd(0xc4202ad528, 0xc4203c80f0, 0x0): /Users/rjkroege/tools/gopkg/src/github.com/rjkroege/edwood/ecmd.go:204 +0x20

Aside: there were more go routines with the same stack dump that crashed at the same time.

I think the crash was fixed by a0d6ffdeb34a23ba6fff70a452a14d27a0df4143, which made editerror properly terminate the goroutine. I can't reproduce it anymore.
