[Distutils] request: make versions which include svn revision numbers look the same with distutils and with setuptools

[zooko]

Folks:

I'm trying to get the Nevow project to accept a patch [1] that makes  
it easier to use Nevow with setuptools, even though the maintainers  
of Nevow passionately hate setuptools.

In such a situation, any tiny unnecessary difference between  
distutils behavior and setuptools behavior is another grain of sand  
in the gears.

So with the patch that I've offered to Nevow, if you run "./setup.py  
sdist" without setuptools installed, you get:

Nevow-0.9.31+r15049.tar.gz

and if you run "./setup.py sdist" with setuptools installed, you get:

Nevow-0.9.31-r15049.tar.gz

Why are the version numbers different?  I personally prefer the '-'  
instead of the '+' in the version number, and I would be happy if  
distutils in Python 2.4.5 used '-'.  However, unless the distutils is  
going to start using '-', then I suggest that setuptools v0.6 final  
also use '+', so that there is one less thing that is different.

Regards,

Zooko
