More precise instructions about installing from git

Hi everybody,
just now I noticed that I was still running the old SVN version of
matplotlib and not the most recent one from git. Apparently the files
installed to (in my
case) /usr/local/lib/python2.6/dist-packages/matplotlib from SVN with
"python setup.py install" took precedence over the installation with
"python setupegg.py develop". I therefore suggest to modify
http://matplotlib.sourceforge.net/faq/installing_faq.html#install-from-git by replacing

"If you want to be able to follow the development branch as it changes
just replace the last step with (make sure you have setuptools
installed):"

with

"If you want to be able to follow the development branch as it changes
just uninstall any existing copy of matplotlib and replace the last step
with (make sure you have setuptools installed):"

Best wishes,
Dieter
