Updates to 1996/huffman - format + bugs + try.sh

The try.sh script runs the commands in the try section. It does not run
the spoiler command in the judges' remarks as that didn't feel like a
good idea.

The README.md has been typo and format checked.

Added to bugs.md to try and change to use fgets(3). In the meantime it
uses 2>/dev/null.
