Description

When compressing an archive like .tar, if the output file is inside of the input folder, Ouch enters an infinite compression state.

That's because the output is being considered as the output, so any written bytes are read again, and again, and that's an infinite loop.

Current Behavior

$ ouch compress . archive.tar

Runs forever and will slowly exhaust all your hard drive space.

Example compressing a 2 GB folder:

Expected Behavior

Ouch should ignore the output as the input file, like tar util does.

$ tar -cvf archive.tar .
...
...
tar: ./out.tar: file is the archive; not dumped

Additional Information

There is a check for skipping input files that are the same as the output file at

But in this case it's necessary to check while iterating in folder structures.
