Update

As SO user avivir correctly notes "split", might be a valid option.

Answer 1

If you want to add only a part of a hunk, you can select edit from the menu that gets displayed:

Stage this hunk [y,n,q,a,d,/,e,?]?

This will start your editor where you can delete unwanted lines from the hunk that is about to be added to the index. The change is virtual, that is your file will not change.
