I'm working on systematically going through the CodeCoverage to see what areas have gaps to add testing for. I saw that for the base encoding bins the uu_app did not have coverage and it was because it was following a format where the code to create the command was being duplicated. I did a bit of a refactor so that the code to create the uu_app can follow a similar format of all of the other bins. This also has the side effect of increasing the code coverage.
I also noticed that the code that tests the buffering when encoding did not have a test to cover that use case, so I added a very basic one to go through that code path and validate that the output is still being converted correctly.
