There is no way to differentiate between "do not use color" and "no
value found". This makes it impossible to use this to implement the
required "try color.diff, fallback to diff.color" behavior.
We could simply make it
git config --get-colorbool diff
which would check both (and when diff.color support is finally dropped,
just remove it from there).
git-svn should probably be moved to this interface (it still has the
color.diff == true means "always" behavior), but it can't be until the
fallback behavior is implemented.
Also, your patch doesn't seem to implement the color.pager/pager.color
behavior, either (which is probably not important for git-add -i, but is
used by git-svn).
Anyway, below is a totally untested (I don't even have svn installed,
but it passes perl -wc!) patch for git-svn to use the new "true means
auto" behavior for color.diff. It would be nice to replace this with
a working --get-colorbool, but we should at least unify the behavior
before v1.5.4.
