I'm open to config files accepting hyphens as well as underscores.  The
current config parsing code was thrown together pretty quickly, and yes
it *does* use ConfigParser.  Accepting hyphens would make the
documentation a bit simpler, which is always a good metric of software

The no_default vs. use_defaults could definitely be massaged a bit.
It's not documented at *all*; in fact, the docs as written would lead
you to believe that anything you see in "--help" output can be used in a
config file (modulo the underscore/hyphen thingy).

But that's not so: some options are just "negative aliases" for others.
The underlying reason for this is sound (--use-defaults and --no-default 
both set the same instance attribute: 'use_defaults'), but that's just
an explanation, not an excuse.  IMHO the config file should accept as
close to what the command-line accepts as possible: this means hyphens
too, and it means handling "negative alias" options.

Hmmm.  I'll look into it -- just added it to the TODO file, FWIW.
Anyone who wants to give it a shot and submit a patch should look at the
'parse_config_files()' method in dist.py.
