Add option to invert match command selection (#3114)

Browse Source 
* Add option to invert match command selection

* Fix rustfmt error

* Rename match --exclude to --invert

To be more descriptive and conform to e.g. grep or ripgrep -v flag.
Also simplified the --invert flag description.

* Fix formatting when description got shorter
