Feature: Enable piped input
I had a list of files generated by another program that I needed to find duplicates in. I modified fdupes to be able to pipe it a newline-delimited list of absolute file paths to scan for duplicates. Alternatively, I probably could have accomplished this job with fdupes "as is" by creating a bunch of temporary symbolic links in a directory, but the pipe seemed like a cleaner way.
