Even though I think these are both worth fixing, I do not think it should
happen as part of this patch.  Because the code that needs to "fix" the
"extra blank bug" this patch introduces will need to deal with exactly the
same horizon effect as your "deleting c and d at the end will not have the
blank immediately after b in the context" example, I expect we will fix
the fallout from this patch when we fix that "delete c and d at the end"
example.
