Looking at the bug report Philip linked to I think this is a long
standing bug where splitting a patch and then editing one of the
subhunks can fail because git-add--interactive.perl doesn't know how to
stitch the subhunks back together when one of them has been edited.
There's a failing test in t3701-add-interactive.sh to document this. It
is on my radar to fix this (at least in simple cases) but I haven't got
round to it yet.
Thanks Philip for the detailed report
Best Wishes
Phillip
