"""`cat` for Python 3.

 - if a file has no newline at the end then the last line is merged
   with the first line of the next file like `cat` does

 - os.fsencode() is not used to encode error message therefore there
   could be surrogates in the output (encoded using the default for
   errors 'backslashreplace' error handler): it is always possible to
   restore the original filename whatever (ascii-based) locale
