I would play around in lib/vclib/ccvs/bincvs.py:BinCVSRepository.rawdiff()
using some file-based debugging statements such as:

   open('/path/to/debug/logfile', 'a').write("This is a debug statement\n")

For example, you might add the line below (which appends a stringified form
of the list "args" to a file):

    open('/tmp/VIEWVCLOG', 'a').write(str(args) + "\n")

just before this statement in the function:

    fp = self.rcs_popen('rcsdiff', args, 'rt')

When I do so and then view a CVS diff, the file /tmp/VIEWVCLOG is created
(if it didn't already exist), and the following line is appended to it:

   ['-u', '-r1.10', '-r1.11', '/usr/local/cvs/ViewCVS/viewcvs/CHANGES,v']

Be aware that if you're running ViewVC under mod_python or mod_wsgi, you
might have to restart your web server every time you make a change to a
Python module in order for your new code to get executed.
