Sure. Python itself. Do a checkout of the code from Subversion then for
any given file just ask Subversion for a diff between it and the previous
version. For example:
% pwd
/Users/skip/src/python/trunk
% svn info Lib/os.py
Path: Lib/os.py
Name: os.py
URL: svn+ssh://[EMAIL PROTECTED]/python/trunk/Lib/os.py
Repository Root: svn+ssh://[EMAIL PROTECTED]
Repository UUID: 6015fed2-1504-0410-9fe1-9d1591cc4771
Revision: 67276

Remove references to platform 'mac'
The 'mac' platform (that is, os.name == 'mac') was used for the MacOS 9
port,
which is no longer supported (as of Python 2.4 IIRC).

And so on. In general, any open source project should be available in this
fashion. The details for fetching diffs will depend on the specific source
code control system being used.
