Fixes:
* Short options cannot be repeated in the same group:
e.g., `-nn` fails, but `--null-input --null-input` works
* Short options are processed in an arbitrary fixed order, not the order
given by the user: e.g., `-hV`, `-Vh`, `-h -V`, and `--help --version`
are processed as `-h`, but `-V -h` and `--version --help` are
processed as `-V`
* `-L` cannot be a part of a short option group (as the last one):
e.g., `-nLlib` and `-nL lib` fail
Before, arrays would not reset colors after `[` and `,`, but objects
would; it would reset colors twice before `]` and `}`; and some cases of
indentation would have colors applied. Now, colors are reset immediately
after any token that is colored, before any indentation. This makes the
formatting consistent, for the benefit of custom `JQ_COLORS`.
