setup: prevent setuptools from laying an egg
Previously, test-hghave.t was failing on Windows (and on Linux if
$FORCE_SETUPTOOLS was set) with the following:

Augie relayed concerns[1] about the first attempt at this, which also excluded
'install_egg_info'. All that needs to be excluded to avoid the egg and make the
test work is to filter out 'bdist_egg'. (Actually, the body of this class could
simply be 'pass', and 'bdist_egg' still isn't run. But that seems to magical.)
Also note that prior to this (and still now), `make clean` doesn't delete the
'mercurial.egg-info' that is generated by `make install`.

Mercurial's documentation is kept in reStructuredText format, which is
a simple plain text format that's easy to read and edit:
http://docutils.sourceforge.net/rst.html
It's also convertible to a variety of other formats including standard
UNIX man page format and HTML. You'll need to install Docutils:
http://docutils.sourceforge.net/
Use the Makefile in this directory to generate the man and HTML pages.
