Progress: Continue working on completing the remove program.

Complete the recursion logic.
There wasn't much left to do at glance.
Additional testing will weed out any remaining incomplete functionality.

This should leaves:
  - The remaining `@todo` notes.
  - Any remaining advanced matching (if any).
  - Adding runtime tests.

A note about adding unit or runtime tests.
I am thinking that I need to mock all of the remove functions.
These mocked functions will write a flag bit in something that will designate all of the removed files.
This result of marked removals can be matched to the expected removals.
This could operate like a combination of a unit test and a runtime test (unit test over the main program, which would be effectively the same as a runtime test in some ways).
