In case the cursor is inside an insert redline, then .uno:ReinstateTrackedChange works for that change, but if it's inside a delete redline, then nothing happens. This is because SwEditShell::ReinstatePaM() only handles insertions, where reinstate/reject means a deletion. Extend this to have basic support for reinstating a deletion: insert the same string after the redline. This is just initial support, multi-paragraph and multi-portion redlines are not yet handled.
