Fix Ctrl-Backspace and Ctrl-Del.

There were two problems here:

1. dir was passed into ctrlDeleteDir, but was ignored, so Ctrl-Del
behaved the same as Ctrl-Backspace.
2. dir was not being passed to deleteDir in the short-circuit case,
which caused a prayer that expected a direction in deleteDir to fail.

Adds some test coverage to both the non-empty and empty-cases of
ctrlDeleteDir.
