clap/clap_bench/benches/05_ripgrep.rs
Ed Page 470531b515 fix!: Replace multiple_values with number_of_values 
This reduces ambiguity in how the different "multiple" parts of the API
interact and lowrs the amount of API surface area users have to dig
through to use clap.

For now, this is only a matter of cleaning up the public API.  Cleaning
up the implementation is the next step.
