- Added support for character ranges ( a-z )
- Added support for complementary charset ( -c ), only in delete mode
- Added support for octal escape sequences

otherwise behavior is not predictable at first sight.
- tr now supports null characters in the input
- Does not yet have support for character classes ( [:upper:] )
*sum tools: -c was added
tr: -d flag was added.
xargs: -n flag was added.
