Edit mode should allow me to add lines

[MMI]

I should be able to type in more code when I'm in edit mode. The use case is kind of like this:

I'm merging some C header file stuff and I need to keep both sides... so I add #ifdef SOME_LABEL at the top of the right side block, and a #else at the bottom. The I right-arrow to bring the left side block over and double click to enter edit mode -- I cannot add a new line for the #endif -- I can only add text to the last line of the merged block.

Thanks for the report. Currently there is no logic for adding lines and editing is only allowed for existing lines. But I will see what I can do.
