[PATCH 4/4] name-rev: ease up condition

[Stefan Beller <stefanbeller@googlemail.com>]

Now that the internal variables 'all' and 'transform_stdin' are read in
by OPT_BOOL, which makes sure to have the variable being 0 or 1 after
reading, we do not need the double negation to map any other value to
1.
