[PATCH] new test fails "add -p" for adds on the top line

[Matt Graham <mdg149@gmail.com>]

add -p doesn't work for some diffs.  diffs adding a new line at the top of
the file with other adds later in the file are one way to trigger the problem.

during add -p, split the diff and then answer y for all segments.  the file
won't have been added to the index.
