[PATCH] add -p: skip conflicted paths

When performing "git add -p" on a file in a conflicted state, we
currently spew the diff and terminate the process.

This is not very helpful to the user. Change the behaviour to
skipping the file, while outputting a warning.

OK, here's a quick stab at fixing the "add -p" issue. Note that
I'm not very fluent in Perl, so apologies if this is not up to
standards.
