Ok, the commands behave like makefile rules, once run they don't run 

But there are still several issues here:

Remember that I said that my goal with 'bdist_deb' was for users to have 
a SINGLE command to generate a .deb.

What needs to be achieved is for a command like this:
$ python setup.py  bdist_deb
$ python setup.py  bdist_deb  --ignore-single-version-externally-managed

to be possible.  'bdist_deb' would call sdist_dsc internally with the 
necessary args WITHOUT having to explicitly put 'sdist_dsc' on the 
command line.

This is how I was expecting that you would implement the bdist_deb 
command inside of stdeb.

Another issue:  In util.py on line 962 (gerry-reno git):
%(setup_env_vars)spython$* -c "import 
install \\

Maybe it should be like this (note semicolon splitting line into two 
%(setup_env_vars)s;    python$* -c "import 
install \\

Otherwise any of the env vars don't seem to be in effect for the  line 
itself.   If you put any of the env vars in the line, they don't expand 
to the value set in set_env_vars.  They expand to previous value or to null.
