How to override project configuration options without parameters?

[lackovic]

.rspec-local allow individual developers to set options that override the common project options in .rspec (see Read command line configuration options from files).

It is clear how to add options and change options which accept arguments, but how do you disable/suppress common project options that don't accept any argument?

For example, given the following .rspec:

--backtrace

What should developers write in their .rspec-local to disable backtracing?

• Ruby version: 2.5.3
• rspec-core version: 3.8

Do you suggest a --no-backtrace option to override a project-level --backtrace just like --no-color/--no-profile do?
You may start here and draw some inspiration here for the start if you would like to tackle adding this option @lackovic. Some changes to docs and tests will come along, but worry not, we'll help you along the way.

That seems like it will do! Thanks for the hints, I will gladly work on this as soon as I find the time.
