Let's rename "--internal-diff" to "--no-ext-diff", just for ease of
memory for those who use both Svn and Git.

You know what? I like that reasoning.

We could still have a "--internal-diff" (or "--no-ext-diff") for
user-friendliness reasons, but define it as an alias for
"--diff-cmd=''". That would have the advantage of making clear how
those two options would interact if both are specified.
