description:
indent: check command line options stricter
Previously, bool options were allowed to have trailing garbage. For
example, the option '-bacc' could be spelled '-bacchus' as well.
Check that the exact option name is given in the command line, to
prevent typos in the configuration files and to reduce surprises just in
case a future option is a prefix of an existing option, or vice versa.
Add a new test program for error handling. Most of these tests are so
simple that it would be overkill to create 3 files for each test.
