Re: [RFC PATCH 1/2] Fix applying a line when all following lines are deletions

If a diff looked like
 @@
  context
 -del1
 -del2
and you wanted to stage the deletion 'del1', the generated patch
wouldn't apply because it was missing the line 'del2' converted to
context, but this line was counted in the @@-line
