Controlled by new configuration option

"git add" to pass a command-line option like "--word-diff=color" to
git-add--interactive.perl, so a configuration option is the only
lightweight solution.

With this feature, the added or deleted form of a hunk can be empty,
so made some necessary checks for $_ being defined.

Hmm. We can't apply a word-diff, so presumably your "permit" here is
just for the display, replacing the colorized bits. And that looks like
what your patch does.

Note that the number of lines in your --word-diff=color hunk and the
actual diff will not necessarily be the same.  What happens if I split a
hunk with your patch?
