Mike,
After I pulled the updates from github today, dwcommand.py has "unreachable code" on line 447. (this is the line number of the "unreachable code" in my editor. But when I look at offending line number in Github, it's completely different.

It also looks like there's an indentation issue throughout the file.
Didn't we have some indentation issues previously- when I first got involved with the project?
