Describe the enhancement and the motivation for it.
It would be nice if there was a manual line-alignment option like in kdiff3. The reason is that often times the automatically generated diff will misalign lines & it would help the reviewer be able to adjust that to make the review easier to read. The manual alignment can be persisted so that others benefit. It should be visible where there is a manual alignment. It should be possible to remove a single manual alignment & all manual alignments.
