Long-term, we want both of those. When we have pluggable diff
programs, users will always have the case where for *just this
run* they want to use a different diff program than what's
specified in the config files. It just so happens that we can
also make use of that code path and command-line option today to
switch between the internal and GNU diff implementations.

So my vote goes to making the internal library the default,
changeable only at run-time with some kind of --diff-program
option.

I'm not sure what the answer to this is, but the --diff-program
option will need a way to get command-line arguments to the
program. Whether it should be made of the form --diff-program
'/usr/bin/diff -up' or --diff-program /usr/bin/diff -x -up i am
not sure. I lean toward the former, but i'm sure some people
will cry about spaces in their filenames.
